Flip3D is pretty much the most useless feature in Windows Vista (and 7). It’s slower than Alt+Tab and pretty much completely worthless in every way. You’d be much better off using one of the Expose clones out there (Switcher, MyExpose, SmartFlip, etc) or you can completely disable this feature with a simple registry patch.
Note: For those of you unaware of what it is, you can use Win+Tab to bring up Flip3D to see what the fuss is about. It looks like this:
Disable Flip 3D
Extract the zip file to your hard drive and then double-click on DisableFlip3D.reg to enter the information into the registry.
Next, you will have to open an Administrator mode command prompt by right-clicking on the command prompt and selecting Run as Administrator. Run these commands, which will restart the desktop window manager service.
net stop uxsms
net start uxsms
Re-Enable Flip 3D
Extract the zip file to your hard drive and then double-click on EnableFlip3D.reg to enter the information into the registry.
Follow the steps above to restart the desktop window manager service.
