The transparent glass look of Aero Glass in Windows 7 and Vista may look nice, but it also may slow down computers that don’t have powerful video adapters. If the performance of your computer is being adversely affected by the Aero Glass feature, you can speed up Windows and still benefit from the Aero features, such as Flip 3D and Taskbar thumbnails. The glass transparency can be disabled.

This article shows you how to do this in Windows 7 and Vista. The procedure is slightly different in each system.

Windows 7

The following Windows Explorer window shows the Aero Glass transparency effect in Windows 7. You’ll notice that you can see the Windows logo on the desktop through the window’s border.
