13. 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.
14. 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.
15. 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. This isn't fully implemented in the beta yet, but Long Zheng has created a few sample themes to illustrate how it works. And Jamie Thompson takes this even further, with a theme that always displays the latest BBC news and weather on your desktop.
16. 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.
17. 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.
18. 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.
19. 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.
20. 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.
21. Remove 'Send Feedback'
Microsoft has released Windows 7 to get feedback from the public, so it's important to take advantage of that. If you don't like something, or have a good idea, then click Send Feedback and tell them what's on your mind. You really could make a difference. But once you've done all that then you might want to get rid of the Send Feedback links on your windows, and this is very easy to do. Just launch REGEDIT, go to HKEY_CURRENT_USER\Control Panel\Desktop, set the FeedbackToolEnabled value to zero and restart your PC. (Set it to 3 if you'd like the Send Feedback links back again.)
22. 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'.
23. 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.
