This article will tell you how to disable Flip 3D in Windows Vista. Vista Ultimate, Business or Enterprise users can do it through Group Policy.

But editing the registry works for all.

Open Regedit and navigate to key

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DWM

If the key DWM does not exist, rt click on Windows and create a new key.

Name it as DWM.

Next, in RHS panel, rt click on blank space and create a new DWORD (32-bit) Value by right click on any blank space.

Select New. Assign DisallowFlip3d as the value name, and set its value data as 1 (0×00000001).

Exit Regedit.

This will diable Flip 3D.

To re-enable it, simply delete this DWM key.

That’s it!
