Whether you've just bought a new PC running Windows 7 or you've  been using it for a while, there are bound to be things you didn't know  you could do.
Whether it's tweaks to get the desktop the way you  want it, tips for troubleshooting or ways to squeeze more performance  from Windows 7, we've got it covered.
We've updated our popular  Windows 7 tips article with a load of new ones, including how to recover  locked-up apps, how to extend your jumplists, leave a Windows 7  Homegroup, and more. Read on for 85 tips to help you get the best from  Windows 7.
1. Problem Steps Recorder
As  the local PC guru you're probably very used to friends and family  asking for help with their computer problems, yet having no idea how to  clearly describe what's going on. It's frustrating, but Microsoft feels  your pain, and Windows 7 will include an excellent new solution in the  Problem Steps Recorder.
When any app starts misbehaving under  Windows 7 then all your friends need do is click Start, type PSR and  press Enter, then click Start Record. If they then work through whatever  they're doing then the Problem Steps Recorder will record every click  and keypress, take screen grabs, and package everything up into a single  zipped MHTML file when they're finished, ready for emailing to you.  It's quick, easy and effective, and will save you hours of  troubleshooting time.
2. Burn images
Windows  7 finally introduces a feature that other operating systems have had  for years - the ability to burn ISO images to CDs or DVDs. And it  couldn't be much easier to use. Just double-click the ISO image, choose  the drive with the blank disc, click Burn and watch as your disc is  created.
3. Create and mount VHD files
Microsoft's  Virtual PC creates its virtual machine hard drives in VHD files, and  Windows 7 can now mount these directly so you can access them in the  host system. Click Start, type diskmgmt.msc and press Enter, then click  Action > Attach VHD and choose the file you'd like to mount. It will  then appear as a virtual drive in Explorer and can be accessed, copied  or written just like any other drive.
Click Action > Create VHD  and you can now create a new virtual drive of your own (right-click it,  select Initialise Disk, and after it's set up right-click the  unallocated space and select New Simple Volume to set this up). Again,  you'll be left with a virtual drive that behaves just like any other,  where you can drag and drop files, install programs, test partitioning  software or do whatever you like. But it's actually just this VHD file  on your real hard drive which you can easily back up or share with  others. Right-click the disk (that's the left-hand label that says "Disk  2" or whatever) and select Detach VHD to remove it.
The command  line DISKPART utility has also been upgraded with tools to detach a VHD  file, and an EXPAND command to increase a virtual disk's maximum size.  Don't play around with this unless you know what you're doing, though -  it's all too easy to trash your system.
4. Troubleshoot problems
If  some part of Windows 7 is behaving strangely, and you don't know why,  then click Control Panel > Find and fix problems (or  'Troubleshooting') to access the new troubleshooting packs. These are  simple wizards that will resolve common problems, check your settings,  clean up your system and more. 
5. Startup repair
If  you've downloaded Windows 7 (and even if you haven't) it's a good idea  to create a system repair disc straight away in case you run into  problems booting the OS later on. Click Start > Maintenance >  Create a System Repair Disc, and let Windows 7 build a bootable  emergency disc. If the worst does happen then it could be the only way  to get your PC running again.
6. Take control
Tired  of the kids installing dubious software or running applications you'd  rather they left alone? AppLocker is a new Windows 7 feature that  ensures users can only run the programs you specify. Don't worry, that's  easier to set up than it sounds: you can create a rule to allow  everything signed by a particular publisher, so choose Microsoft, say,  and that one rule will let you run all signed Microsoft applications.  Launch GPEDIT.MSC and go to Computer Configuration > Windows Settings  > Security Settings > Application Control Policies > AppLocker  to get a feel for how this works.
7. Calculate more
At  first glance the Windows 7 calculator looks just like Vista's version,  but explore the Mode menu and you'll see powerful new Statistics and  Programmer views. And if you're clueless about bitwise manipulation,  then try the Options menu instead. This offers many different unit  conversions (length, weight, volume and more), date calculations (how  many days between two dates?), and spreadsheet-type templates to help  you calculate vehicle mileage, mortgage rates and more. 
Don't  take any Windows 7 applet at face value, then - there are some very  powerful new features hidden in the background. Be sure to explore every  option in all Windows applets to ensure you don't miss anything  important.
CALCULATE MORE: The new Calculator is packed with useful features and functionality
8. Switch to a projector
Windows  7 now provides a standard way to switch your display from one monitor  to another, or a projector - just press Win+P or run DisplaySwitch.exe  and choose your preferred display. (This will have no effect if you've  only one display connected.)
9. Get a power efficiency report
If  you have a laptop, you can use the efficiency calculator to get Windows  7 to generate loads of useful information about its power consumption.  Used in the right way, this can help you make huge gains in terms of  battery life and performance. To do this you must open a command prompt  as an administrator by typing 'cmd' in Start Search, and when the cmd  icon appears, right-click it and choose Run as administrator.
Then  at the command line, just type in 'powercfg -energy' (without quotes)  and hit Return, and Windows 7 will scan your system looking for ways to  improve power efficiency. It will then publish the results in an HTML  file, usually in the System32 folder. Just follow the path it gives you  to find your report.
10. Understanding System Restore
Using  System Restore in previous versions of Windows has been something of a  gamble. There's no way of telling which applications or drivers it might  affect - you just have to try it and see.
Windows 7 is different.  Right-click Computer, select Properties > System Protection >  System Restore > Next, and choose the restore point you'd like to  use. Click the new button to 'Scan for affected programs' and Windows  will tell you which (if any) programs and drivers will be deleted or  recovered by selecting this restore point. (Read our full Windows 7 System Restore tutorial.)
11. Set the time zone
System  administrators will appreciate the new command line tzutil.exe utility,  which lets you set a PC's time zone from scripts. If you wanted to set a  PC to Greenwich Mean Time, for instance, you'd use the command
tzutil /s "gmt standard time"
The  command "tzutil /g" displays the current time zone, "tzutil /l" lists  all possible time zones, and "tzutil /?" displays details on how the  command works. 
12. Calibrate your screen
The  colours you see on your screen will vary depending on your monitor,  graphics cards settings, lighting and more, yet most people use the same  default Windows colour profile. And that means a digital photo you  think looks perfect might appear very poor to everybody else.  Fortunately Windows 7 now provides a Display Colour Calibration Wizard  that helps you properly set up your brightness, contrast and colour  settings, and a ClearType tuner to ensure text is crisp and sharp. Click  Start, type DCCW and press Enter to give it a try.
13. Clean up Live Essentials
Installing  Windows Live Essentials will get you the new versions of Mail, Movie  Maker, Photo Gallery and others - great. Unfortunately it also includes  other components that may be unnecessary, but if you like to keep a  clean system then these can be quickly removed.
If you left the  default "Set your search provider" option selected during installation,  for instance, Windows Live will install Choice Guard, a tool to set your  browser home page and search engine, and prevent other programs from  changing them. If this causes problems later, or you just decide you  don't need it, then Choice Guard may be removed by clicking Start,  typing msiexec /x  and pressing [Enter].
Windows Live Essentials  also adds an ActiveX Control to help upload your files to Windows Live  SkyDrive, as well as the Windows Live Sign-in Assistant, which makes it  easier to manage and switch between multiple Windows Live accounts. If  you're sure you'll never need either then remove them with the Control  Panel "Uninstall a Program" applet.
14. Add network support
By  default Windows Live MovieMaker won't let you import files over a  network, but a quick Registry tweak will change this. Run REGEDIT,  browse to HKEY_CURRENT_USER\Software\Microsoft\Windows Live\Movie Maker,  add a DWORD value called AllowNetworkFiles and set it to 1 to add  network support.
15. Activate XP mode
If you've old but important software that no longer runs under Windows 7, then you could try using 
XP Mode,  a virtual copy of XP that runs in a window on your Windows 7 desktop.  But there's a big potential problem, as XP Mode only works with systems  that have hardware virtualisation (AMD-V or Intel  VT) built-in and  turned on. If you've a compatible CPU then this may just be a matter of  enabling the option in your BIOS set-up program, however some high  profile brands, including Sony Vaio, disable the setting for "security  reasons". And that blocks XP Mode from working, too.
One solution  has emerged, but it's a little risky, as essentially you'll have to  alter a byte in your laptop firmware and hope this doesn't have any  unexpected side-effects. Gulp. If you're feeling brave then take a look  at the 
Feature Enable Blog for the details, but don't blame us if it goes wrong.
A safer approach might be to use 
VirtualBox,  a virtualisation tool that doesn't insist on hardware support, but then  you will need to find a licensed copy of XP (or whatever other Windows  version your software requires) for its virtual machine.
16. Enable virtual Wi-Fi
Windows  7 includes a little-known new feature called Virtual Wi-Fi, which  effectively turns your PC or laptop into a software-based router. Any  other Wi-Fi-enabled devices within range - a desktop, laptop, an iPod  perhaps - will "see" you as a new network and, once logged on,  immediately be able to share your internet connection.
This will  only work if your wireless adapter driver supports it, though, and not  all do. Check with your adapter manufacturer and make sure you've  installed the very latest drivers to give you the best chance.
Once you have driver support then the easiest approach is to get a network tool that can set up virtual Wi-Fi for you. 
Virtual Router (below) is free, easy to use and should have you sharing your internet connection very quickly.

If  you don't mind working with the command line, though, maybe setting up  some batch files or scripts, then it's not that difficult to set this up  manually. See Turn your Windows 7 laptop into a wireless hotspot for more.
17. Recover locked-up apps
If  an application locks up under a previous version of Windows then there  was nothing you could do about it. A new Windows 7 option, however, can  not only explain the problem, but may get your program working again  without any loss of data.
When the lockup occurs, click Start, type RESMON and click the RESMON.EXE link to launch the Resource Monitor.
Find your frozen process in the CPU pane (it should be highlighted in red), right-click it and select Analyze Wait Chain.
If  you see at least two processes in the list, then the lowest, at the end  of the tree, is the one holding up your program. If it's not a vital  Windows component, or anything else critical, then save any work in  other open applications, check the box next to this process, click End  Process, and your locked-up program will often spring back to life.
18. Fault-Tolerant Help
Windows  7 includes a new feature called the Fault Tolerant Help (FTH), a clever  technology that looks out for unstable processes, detects those that  may be crashing due to memory issues, and applies several real-time  fixes to try and help. If these work, that's fine - if not, the fixes  will be undone and they won't be applied to that process again.
While  this is very good in theory, it can leave you confused as some  applications crash, then start working (sometimes) for no apparent  reason. So if you'd like to check if the FTH is running on your PC,  launch REGEDIT, and go to HKEY_LOCAL_MACHINE\Software\Microsoft\FTH -  any program currently being protected by the FTH will be listed in the  State key.
Experienced users may also try tweaking the FTH  settings to catch more problems, and perhaps improve system stability. A  post on Microsoft's Ask The Performance Team blog (bit.ly/d1JStu)  explains what the various FTH Registry keys mean.
19. Automatically switch your default printer
Windows  7's location-aware printing allows the operating system to  automatically switch your default printer as you move from one network  to another.
To set this up, first click Start, type Devices, and click the Devices and Printers link.
Select  a printer and click Manage Default Printers (this is only visible on a  mobile device, like a laptop - you won't see it on a PC).
Choose  the "Change my default printer when I change networks" option, select a  network, the default printer you'd like to use, and click Add.
Repeat the process for other networks available, and pick a default printer for each one.
And  now, as you connect to a new network, Windows 7 will check this list  and set the default printer to the one that you've defined.
20. Explore God Mode
Windows 7 has  changed Control Panel a little, but it's still too difficult to locate  all the applets and options that you might need. God Mode, however,  while not being particularly godlike, does offer an easier way to access  everything you could want from a single folder.
To try this out, create a new folder and rename it to:

The  first part, "Everything" will be the folder name, and can be whatever  you want: "Super Control Panel", "Advanced", "God Mode" if you prefer.
The  extension, ED7BA470-8E54-465E-825C-99712043E01C, must be entered  exactly as it is here, though, including the curly brackets. When you  press [Enter] this part of the name will disappear, and double-clicking  the new folder will display shortcuts to functions in the Action Centre,  the Network and Sharing Centre, Power options, troubleshooting tools,  user accounts and others - more than 260 options in total.
21. Right-click everything
At  first glance Windows 7 bears a striking resemblance to Vista, but  there's an easy way to begin spotting the differences - just right-click  things.
Right-click an empty part of the desktop, for instance,  and you'll find a menu entry to set your screen resolution. No need to  go browsing through the display settings any more.
Right-click the  Explorer icon on the taskbar for speedy access to common system  folders: Documents, Pictures, the Windows folder, and more.
And if  you don't plan on using Internet Explorer then you probably won't want  its icon permanently displayed on the taskbar. Right-click the icon,  select 'Unpin this program from the taskbar', then go install Firefox,  instead.
22. Display the old taskbar button context menu
Right-click  a taskbar button, though, and you'll now see its jumplist menu. That's a  useful new feature, but not much help if you want to access the  minimize, maximize, or move options that used to be available.  Fortunately there's an easy way to get the old context menu back - just  hold down Ctrl and Shift as you right-click the taskbar button.
23. Desktop slideshow
Windows  7 comes with some very attractive new wallpapers, and it's not always  easy to decide which one you like the best. So why not let choose a few,  and let Windows display them all in a desktop slideshow? Right-click an  empty part of the desktop, select Personalise > Desktop Background,  then hold down Ctrl as you click on the images you like. Choose how  often you'd like the images to be changed (anything from daily to once  every 10 seconds), select Shuffle if you'd like the backgrounds to  appear in a random order, then click Save Changes and enjoy the show.
DESKTOP SLIDESHOW: Select multiple background images and Windows will cycle through them
24. RSS-powered wallpaper
And  if a slideshow based on your standard wallpaper isn't enough, then you  can always create a theme that extracts images from an RSS feed. For  example, Long Zheng has created 
a few sample themes to illustrate how it works. Jamie Thompson 
takes this even further, with a theme that always displays the latest BBC news and weather on your desktop. And 
MakeUseOf  have a quick and easy tutorial showing how RSS can get you those  gorgeous Bing photographs as your wallpaper. Or you can watch our custom theme video tutorial.
25. Customise the log-on screen
Changing  the Windows log-on screen used to involve some complicated and  potentially dangerous hacks, but not any more - Windows 7 makes it easy.  
First, browse to  HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background  in REGEDIT, double-click the DWORD key called OEMBackground (not there?  Create it) and set its value to 1.
Now find a background image  you'd like to use. Make sure it's less than 256KB in size, and matches  the aspect ratio of your screen as it'll be stretched to fit.
Next,  copy that image into the %windir%\system32\oobe\info\backgrounds folder  (create the info\backgrounds folders if they don't exist). Rename the  image to backgroundDefault.jpg, reboot, and you should now have a custom  log-on image.
Alternatively, use a free tweaking tool to handle everything for you. 
Logon Changer displays a preview so you can see how the log-on screen will look without rebooting, while the 
Logon Screen Rotator accepts multiple images and will display a different one every time you log on.
26. Recover screen space
The  new Windows 7 taskbar acts as one big quick launch toolbar that can  hold whatever program shortcuts you like (just right-click one and  select Pin To Taskbar). And that's fine, except it does consume a little  more screen real estate than we'd like. Shrink it to a more manageable  size by right-clicking the Start orb, then Properties > Taskbar >  Use small icons > OK.
27. Enjoy a retro taskbar
Windows  7 now combines taskbar buttons in a way that saves space, but also  makes it more difficult to tell at a glance whether an icon represents a  running application or a shortcut. If you prefer a more traditional  approach, then right-click the taskbar, select Properties, and set  Taskbar Buttons to "Combine when taskbar is full". You'll now get a  clear and separate button for each running application, making them much  easier to identify.
28. Remove taskbar buttons
One  problem with the previous tip is the buttons will gobble up valuable  taskbar real estate, but you can reduce the impact of this by removing  their text captions. Launch REGEDIT, browse to HKEY_CURRENT_USER\Control  Panel\Desktop\WindowMetrics, add a string called MinWidth, set it to  54, and reboot to see the results.
29. Restore the Quick Launch Toolbar
If  you're unhappy with the new taskbar, even after shrinking it, then it  only takes a moment to restore the old Quick Launch Toolbar.
Right-click  the taskbar, choose Toolbars > New Toolbar, type  "%UserProfile%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch"  (less the quotes) into the Folder box and click Select Folder. 
Now  right-click the taskbar, clear 'Lock the taskbar', and you should see  the Quick Launch toolbar, probably to the right. Right-click its  divider, clear Show Text and Show Title to minimise the space it takes  up. Complete the job by right-clicking the bar and selecting View >  Small Icons for the true retro look.
30. Custom power switch
By  default, Windows 7 displays a plain text 'Shut down' button on the  Start menu, but it only takes a moment to change this action to  something else. If you reboot your PC a few times every day then that  might make more sense as a default action: right-click the Start orb,  select Properties and set the 'Power boot action' to 'Restart' to make  it happen.
31. Auto arrange your desktop
If  your Windows 7 desktop has icons scattered everywhere then you could  right-click it and select View > Auto arrange, just as in Vista. But a  simpler solution is just to press and hold down F5, and Windows will  automatically arrange its icons for you.
32. Disable smart window arrangement
Windows  7 features interesting new ways to intelligently arrange your windows,  so that (for example) if you drag a window to the top of the screen then  it will maximise. We like the new system, but if you find it  distracting then it's easily disabled. Run REGEDIT, go to  HKEY_CURRENT_USER\Control Panel\Desktop, set WindowArrangementActive to  0, reboot, and your windows will behave just as they always did. 
33. Browse your tasks
If  you prefer the keyboard over the mouse, you will love browsing the  taskbar using this nifty shortcut. Press Windows and T, and you move the  focus to the left-most icon on the taskbar. Then use your arrow keys to  change the focus to other icons, and you get a live preview of every  window.
34. Display your drives
Click  Computer in Windows 7 and you might see a strange lack of drives, but  don't panic, it's just Microsoft trying to be helpful: drives like  memory card readers are no longer displayed if they're empty. We think  it's an improvement, but if you disagree then it's easy to get your  empty drives back. Launch Explorer, click Tools > Folder Options >  View and clear 'Hide empty drives in the computer folder'.
35. See more detail
The  new and improved Windows 7 magnifier offers a much easier way to zoom  in on any area of the screen. Launch it and you can now define a scale  factor and docking position, and once activated it can track your  keyboard focus around the screen. Press Tab as you move around a dialog  box, say, and it'll automatically zoom in on the currently active  control.
36. Extend your jumplists
By  default a jumplist will display up to 10 items, but it can often be  useful to extend this and add a few more. Right-click Start, select  Properties > Customize and set "Number of recent items to display in  Jump Lists" to the figure you need.
37. Disable Aero Peek
Hover  your mouse cursor over the bottom right hand corner of the screen and  Windows 7 will hide open windows, showing you the desktop. Seems like a  good idea to us, but if the feature gets in your way then it's easy to  turn off. Simply right-click the Start orb, select Properties >  Taskbar and clear the "Use Aero Peek to preview the desktop" box.
38. Pin a drive to the taskbar
The taskbar isn't just for apps and documents. With just a few seconds work you can pin drive icons there, too.
Right-click  an empty part of the desktop, select New > Text File, and rename the  file to drive.exe. Drag and drop this onto your taskbar, then delete  the original file.
Right-click your new "drive.exe" taskbar  button, then right-click its file name and select Properties. Change the  contents of both the Target and Start In boxes to point at the drive or  folder of your choice, perhaps click Change Icon to choose an  appropriate drive icon, and you're done - that drive or folder is now  available at a click.
39. Expand your taskbar previews
Move  your mouse cursor over a Windows 7 taskbar button and you'll see a  small preview of the application window. To make this larger, launch  REGEDIT, browse to  HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband,  right-click in the right hand pane and create a new DWORD value called  MinThumbSizePx. Double-click this, choose the Decimal option, set the  value to 350 and reboot to see the results. Tweak the value again to  fine-tune the results, or delete it to return to the default thumbnail  size.

 
40. Hiding the Windows Live Messenger icon
If  you use Windows Live Messenger a lot, you'll have noticed that the icon  now resides on the taskbar, where you can easily change status and  quickly send an IM to someone. If you prefer to keep Windows Live  Messenger in the system tray, where it's been for previous releases,  just close Windows Live Messenger, edit the shortcut properties and set  the application to run in Windows Vista compatibility mode.
41. Customise UAC
Windows  Vista's User Account Control was a good idea in practice, but poor  implementation put many people off - it raised far too many alerts.  Fortunately Windows 7 displays less warnings by default, and lets you  further fine-tune UAC to suit your preferred balance between security  and a pop-up free life (Start > Control Panel > Change User  Account Control Settings).
42. Use Sticky Notes
The  Sticky Notes app is both simpler and more useful in Windows 7. Launch  StikyNot.exe and you can type notes at the keyboard; right-click a note  to change its colour; click the + sign on the note title bar to add  another note; and click a note and press Alt + 4 to close the note  windows (your notes are automatically saved).
43. Open folder in new process
By  default Windows 7 opens folders in the same process. This saves system  resources, but means one folder crash can bring down the entire shell.  If your system seems unstable, or you're doing something in Explorer  that regularly seems to causes crashes, then open Computer, hold down  Shift, right-click on your drive and select Open in New Process. The  folder will now be launched in a separate process, and so a crash is  less likely to affect anything else.
44. Watch more videos
Windows  Media Player 12 is a powerful program, but it still won't play all the  audio and video files you'll find online. Fortunately the first freeware  Windows 7 codecs package [shark007.net/win7codecs.html] has been  released, and installing it could get your troublesome multimedia files  playing again.
45. Preview fonts
Open the  Fonts window in Windows XP and Vista and you'll see the font names,  probably with icons to tell you whether they're TrueType or OpenType,  but that's about it. Windows 7 sees some useful font-related  improvements.
Open the new fonts window and you'll find a little  preview for every font, giving you a quick idea of how they're going to  look. 
The tedium of scrolling through multiple entries for each  family, like Times New Roman, Times New Roman Bold, Times New Roman Bold  Italic and so on, has finally ended. There's now just a single entry  for each font (though you can still see all other members of the  family).
And there's a new OpenType font, Gabriola, added to the  mix. It's an attractive script font, well worth a try the next time you  need a stylish document that stands out from the crowd.
46. Restore your gadgets
Windows  7 has tightened up its security by refusing to run gadgets if UAC has  been turned off, so limiting the damage malicious unsigned gadgets can  do to your system. If you've disabled UAC, miss your gadgets and are  happy to accept the security risk, though, there's an easy Registry way  to get everything back to normal. Run REGEDIT, go to  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Sidebar\Settings,  create a new DWORD value called AllowElevatedProcess and set it to 1.  Your gadgets should start working again right away.
47. New WordPad formats
By  default WordPad will save documents in Rich Text Format, just as  before. But browse the Save As Format list and you'll see you can also  save (or open, actually) files in the Office 2007 .docx or OpenDocument  .odt formats.
48. Protect your data
USB  flash drives are convenient, portable, and very easy to lose. Which is a  problem, especially if they're carrying sensitive data. Fortunately  Windows 7 has the solution: encrypt your documents with an extension of  Microsoft's BitLocker technology, and only someone with the password  will be able to access it. Right-click your USB flash drive, select Turn  on BitLocker and follow the instructions to protect your private files.
PROTECT YOUR DATA: Your USB flash drives can easily be encrypted with BitLocker
49. Minimise quickly with shake
If  you have multiple windows open on your desktop and things are getting  too cluttered, it used to be a time-consuming process to close them all  down. In Windows 7 you can use the Aero Shake feature to minimise  everything in seconds, using a cool mouse gesture. Grab the title bar of  the window you wish to keep open and give it a shake, and rejoice in a  clear desktop area.
50. Configure your favourite music
The  Windows 7 Media Centre now comes with an option to play your favourite  music, which by default creates a changing list of songs based on your  ratings, how often you play them, and when they were added (it's assumed  you'll prefer songs you've added in the last 30 days). If this doesn't  work then you can tweak how Media Centre decides what a "favourite" tune  is- click Tasks > Settings > Music > Favourite Music and  configure the program to suit your needs.
51. Customise System Restore
There  was very little you could do to configure System Restore in Vista, but  Windows 7 improves the situation with a couple of useful setup options. 
Click  the Start orb, right-click Computer and select Properties > System  Protection > Configure, and set the Max Usage value to a size that  suits your needs (larger to hold more restore points, smaller to save  disk space). 
And if you don't need System Restore to save Windows  settings then choose the "Only restore previous versions of files"  option. Windows 7 won't back up your Registry, which means you'll  squeeze more restore points and file backups into the available disk  space. System Restore is much less likely to get an unbootable PC  working again, though, so use this trick at your own risk.
52. Run As
Hold  down Shift, right-click any program shortcut, and you'll see an option  to run the program as a different user, handy if you're logged in to the  kids' limited account and need to run something with higher privileges.  This isn't really a new feature - Windows XP had a Run As option that  did the same thing - but Microsoft stripped it out of Vista, so it's  good to see it's had a change of heart.
53. Search privacy
By  default Windows 7 will remember your PC search queries, and display the  most recent examples when searching in Windows Explorer. If you're  sharing a PC and don't want everyone to see your searches, then launch  GPEDIT.MSC, go to User Configuration > Administrative Templates >  Windows Components > Windows Explorer, double-click "Turn off display  of recent search entries..." and click Enabled > OK.
54. Tweak PC volume
By  default Windows 7 will now automatically reduce the volume of your PC's  sounds whenever it detects you're making or receiving PC-based phone  calls. If this proves annoying (or maybe you'd like it to turn off other  sounds altogether) then you can easily change the settings accordingly.  Just right-click the speaker icon in your taskbar, select Sounds >  Communications, and tell Windows what you'd like it to do.
55. Rearrange the system tray
With  Windows 7 we finally see system tray icons behave in a similar way to  everything else on the taskbar. So if you want to rearrange them, then  go right ahead, just drag and drop them into the order you like. You can  even move important icons outside of the tray, drop them onto the  desktop, then put them back when you no longer need to keep an eye on  them.
56. Extend your battery life
Windows 7  includes new power options that will help to improve your notebook's  battery life. To see them, click Start, type Power Options and click the  Power Options link, then click Change Plan Settings for your current  plan and select Change Advanced Settings. Expand Multimedia Settings,  for instance, and you'll see a new "playing video" setting that can be  set to optimise power savings rather than performance. Browse through  the other settings and ensure they're set up to suit your needs.
57. Write crash dump files
Windows  7 won't create memory.dmp crash files if you've less than 25GB of free  hard drive space, annoying if you've installed the Windows debugging  tools and want to diagnose your crashes. You can turn this feature off,  though: browse to  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl, create  a new DWORD value called AlwaysKeepMemoryDump, set it to 1, and the  crash dump file will now always be saved.
58. Protect your data
If  you have confidential files in a particular folder or two, and would  like to keep them away from other network users, then right-click the  folder, select Share With > Nobody, and they'll be made private, for  your eyes only (or your user account, anyway).
59. Reorganise the taskbar
Windows  7 taskbar buttons are now movable - feel free to drag, drop and  otherwise reorganise them to suit your needs. And then remember that  each button can be launched by holding with the Windows key and pressing  1 to activate the first, 2 the second and so on, up to 0 for the tenth.
60. Repair your PC
If  Windows 7 won't start, you may not need an installation or repair disc  any more, as the repair environment is now usually installed on your  hard drive. Press [F8] as your PC starts, and if you see a "Repair Your  Computer" option, choose that to see the full range of Windows 7  recovery tools.
61. ReadyBoost revamped
If  you were unimpressed by ReadyBoost in Vista, it may be worth trying the  technology again under Windows 7. The operating system now allows you  to combine multiple USB drives, each with larger caches, to deliver an  extra speed boost.
62. Fixing Windows 7 N
If  you have Windows 7 N then this means you'll be missing key multimedia  applications, like Media Player, Media Centre, DVD Maker and more. But  that's not all. You also won't have some of the subsystems required by  third-party apps like Nero MultiMedia Suite, which means that even if  they install, you could have problems getting them to work correctly. 
Fortunately  there's an easy fix, though, as the missing components are available in  the form of Microsoft's Windows Media Pack. If you're currently having  media-related issues on a Windows 7 N installation, grab your copy from 
support.microsoft.com/kb/968211.
 
63. Find bottlenecks
From what we've seen so  far Windows 7 is already performing better than Vista, but if your PC  seems sluggish then it's now much easier to uncover the bottleneck.  Click Start, type RESMON and press Enter to launch the Resource Monitor,  then click the CPU, Memory, Disk or Network tabs. Windows 7 will  immediately show which processes are hogging the most system resources.
The  CPU view is particularly useful, and provides something like a more  powerful version of Task Manager. If a program has locked up, for  example, then right-click its name in the list and select Analyze  Process. Windows will then try to tell you why it's hanging - the  program might be waiting for another process, perhaps - which could give  you the information you need to fix the problem.

64. Keyboard shortcuts
Windows 7 supports several useful new keyboard shortcuts.
Alt+P
Display/ hide the Explorer preview pane
Windows Logo+G
Display gadgets in front of other windows
Windows Logo++ (plus key)
Zoom in, where appropriate
Windows Logo+- (minus key)
Zoom out, where appropriate
Windows Logo+Up 
Maximise the current window
Windows Logo+Down
Minimise the current window
Windows Logo+Left
Snap to the left hand side of the screen
Windows Logo+Right
Snap to the right hand side of the screen
Windows Logo+Home
Minimise/ restore everything except the current window
65. Drag and drop to the command line
When  working at the command line you'll often need to access files, which  usually means typing lengthy paths and hoping you've got them right. But  Windows 7 offers an easier way. Simply drag and drop the file onto your  command window and the full path will appear, complete with quotes and  ready to be used.
This feature isn't entirely new: you could do  this in Windows XP, too, but drag and drop support disappeared in Vista.  There does seem to be a new Windows 7 complication, though, in that it  only seems to work when you open the command prompt as a regular user.  Run cmd.exe as an administrator and, while it accepts dropped files, the  path doesn't appear.
66. Customise your jumplists
Right-click  an icon on your taskbar, perhaps Notepad, and you'll see a jumplist  menu that provides easy access to the documents you've been working on  recently. But maybe there's another document that you'd like to be  always available? Then drag and drop it onto the taskbar icon, and it'll  be pinned to the top of the jumplist for easier access. Click the pin  to the right of the file name, or right-click it and select "Unpin from  this list" when you need to remove it.
67. Faster program launches
If  you've launched one instance of a program but want to start another,  then don't work your way back through the Start menu. It's much quicker  to just hold down Shift and click on the program's icon (or middle-click  it), and Windows 7 will start a new instance for you.
68. Speedy video access
Want  faster access to your Videos folder? Windows 7 now lets you add it to  the Start menu. Just right-click the Start orb, click Properties >  Start Menu > Customize, and set the Videos option to "Display as a  link". If you've a TV tuner that works with Windows 7 then you'll  appreciate the new option to display the Recorded TV folder on the Start  menu, too.
69. Run web searches
The  Windows 7 search tool can now be easily extended to search online  resources, just as long as someone creates an appropriate search  connector. To add Flickr support, say, visit 
I Started Something,  click Download the Connector, choose the Open option and watch as it's  downloaded (the file is tiny, it'll only take a moment). A "Flickr  Search" option will be added to your Searches folder, and you'll be able  to search images from your desktop.
A multitude of other ready-made searches, such as Google and YouTube, can be downloaded from the 
windowsclub.com website.
70. Schedule Media Centre downloads
You  can now tell Windows Media Centre to download data at a specific time,  perhaps overnight, a useful way to prevent it sapping your bandwidth for  the rest of the day. Launch Media Centre, go to Tasks > Settings  > General > Automatic Download Options, and set the download start  and stop times that you'd like it to use. 
71. Multi-threaded Robocopies
Anyone  who's ever used the excellent command-line robocopy tool will  appreciate the new switches introduced with Windows 7. Our favourite,  /MT, can improve speed by carrying out multi-threaded copies with the  number of threads you specify (you can have up to 128, though that might  be going a little too far). Enter robocopy /? at a command line for the  full details.
72. Load IE faster
Some  Internet Explorer add-ons can take a while to start, dragging down the  browser's performance, but at least IE8 can now point a finger at the  worst resource hogs. Click Tools > Manage Add-ons, check the Load  Time in the right-hand column, and you'll immediately see which browser  extensions are slowing you down.
73. An Alt+Tab alternative
You  want to access one of the five Explorer windows you have open, but  there are so many other programs running that Alt+Tab makes it hard to  pick out what you need. The solution? Hold down the Ctrl key while you  click on the Explorer icon. Windows 7 will then cycle through the  Explorer windows only, a much quicker way to locate the right one. And  of course this works with any application that has multiple windows  open.
74. Block annoying alerts
Just like  Vista, Windows 7 will display a suitably stern warning if it thinks your  antivirus, firewall or other security settings are incorrect.
But  unlike Vista, if you disagree then you can now turn off alerts on  individual topics. If you no longer want to see warnings just because  you've dared to turn off the Windows firewall, say, then click Control  Panel > System and Security > Action Centre > Change Action  Centre settings, clear the Network Firewall box and click OK.
75. Parallel defrags
The  standard Windows 7 defragger offers a little more control than we saw  in Vista, and the command line version also has some interesting new  features. The /r switch will defrag multiple drives in parallel, for  instance (they'll obviously need to be physically separate drives for  this to be useful). The /h switch runs the defrag at a higher than  normal priority, and the /u switch provides regular progress reports so  you can see exactly what's going on. Enter the command 
defrag /c /h /u /r 
in a command window to speedily defrag a system with multiple drives, or enter defrag /? to view the new options for yourself.
76. Fix Explorer
The  Windows 7 Explorer has a couple of potential annoyances. Launching  Computer will no longer display system folders like Control Panel or  Recycle Bin, for instance. And if you're drilling down through a  complicated folder structure in the right-hand pane of Explorer, the  left-hand tree won't always expand to follow what you're doing, which  can make it more difficult to see exactly where you are. Fortunately  there's a quick fix: click Organize > Folder and Search Options,  check "Show all folders" and "Automatically expand to current folder",  and click OK.
77. Faster file handing
If  you hold down Shift while right-clicking a file in Explorer, then you'll  find the Send To file now includes all your main user folders:  Contacts, Documents, Downloads, Music and more. Choose any of these and  your file will be moved there immediately.
78. Create folder favourites
If  you're regularly working on the same folder in Explorer then select it  in the right-hand page, right-click Favourites on the left-hand menu,  and select Add to Favourites. It'll then appear at the bottom of the  favourites list for easy one-click access later.
79. Disable hibernation
By  default Windows 7 will permanently consume a chunk of your hard drive  with its hibernation file, but if you never use sleep, and always turn  your PC off, then this will never actually be used. To disable  hibernation and recover a little hard drive space, launch REGEDIT,  browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power,  then set both HibernateEnabled and HiberFileSizePerfect to zero.
80. Create a new folder shortcut
When  you need to create a new folder in Windows 7 Explorer, don't reach for  the mouse. Just press Ctrl+Shift+N to create the folder in the active  Explorer window, then type its name as usual.
81. Open a jumplist
Most  people right-click a Windows taskbar icon to view its jumplist. You can  also hold the left mouse button over the icon, though, then drag  upwards to reveal the jumplist and choose the option you need, a more  natural action that should be just a little faster.
82. Search quickly
If  you'd like to search for something in an Explorer window then there's  no need to use the mouse. Simply press [F3] to move the focus to the  search box, enter your keyword and press [Enter] to run the search.
83. Search file contents
There's  no obvious way in the Windows interface to search the contents of files  that haven't been indexed, but all you need to do is start your search  with the "content:" search filter. So entering content:Microsoft , for  instance, will find all documents (whether they're actually indexed or  not) that contain the word Microsoft. 
84. Close in a click
Hover  your mouse cursor over a Windows taskbar button will display a preview  thumbnail of that application window. You don't need that app any more?  Then middle-click the thumbnail to close it down.
85. Leave the Homegroup
Homegroups  are an easy way to network Windows 7 PCs, but if you don't use the  feature then turning it off can save you a few system resources.
Click  Start, type Homegroup, and click "Choose homegroup and sharing  options". Click Leave the Homegroup > Leave the Homegroup >  Finish.
Now click Start, type services.msc and press [Enter] to launch the Services Control Panel applet.
Find  and double-click both the HomeGroup Listener and HomeGroup Provider  service, clicking Stop and setting Startup Type to Disabled in each  case, and the services won't be launched when you need reboot.
