Windows 7 gives users better ways to clear most everything but the desktop—namley Aero Shake and Aero Peek. But if you still cling to “Show Desktop,” however, you can kind of get it back.
Pinning a Show Desktop icon to the taskbar in Windows 7 won’t work the way it did in pretty much every earlier version of Windows. While you can still create the “Show Desktop.scf” script, it just won’t pin itself correctly. The Tweaking with Vishal blog offers a kind of work-around that makes use of Windows 7′s utterly transparent toolbars.
The short version: Create a folder, place a “Show Desktop.scf” file in there (either your standard Google-found kind or the script available at the bottom link), then right-click your taskbar to create a “New Toolbar” that points to that folder. Turn off the text and titles on that new toolbar, change the icons to large size, and then put your new one-button toolbar where you’d like.
The drawback: If you pin it too close to the right of your standard tasks and pinned items, you’ll compress them and require an extra click to get to them. If you don’t mind having your desktop button on the left, though, or have a totally re-tweaked taskbar altogether, you’re good to go.
Microsoft offers Windows 7 as a free beta to get feedback on what needs fixing. Still, if you’re endlessly annoyed with the “Send Feedback” link in every single title bar, there’s a way to remove it. Hit the

Once the DVD boots up it’s a simple matter of following along with the fairly simple installation wizard. When you’re choosing installation type, be sure to select Custom (advanced) and choose the partition you set up above. (Be careful here. Choosing the wrong partition could mean wiping your other Windows installation altogether, so make sure you pick the new partition you just created.)
