Flip3D is pretty much the most useless feature in Windows Vista. It's slower than Alt+Tab and pretty much completely worthless in every way. To see it in action, simply press the 'Win+Tab' keys to bring it up. To disable Flip3D, open Notepad and copy this text into it:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DWM] "DisallowFlip3d"=dword:00000001
Now, save the file as 'disableflip3d.reg'. Double-click on the newly created file to enter it into the Registry. Next, right-click on a Command Prompt and select 'Run as Administrator'. First, type in 'net stop uxms' and press Enter. Next, type in 'net start uxms and press Enter again.
To re-enable Flip3D, follow the same steps exactly as above, except add this text into Notepad:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DWM] "DisallowFlip3d"=-
