Change the theme to improve performance

If your computer is working slowly, you might see a message saying that the theme is using most of its allowed memory. If this happens, you can change to the Windows 7 Basic theme or a high-contrast theme to improve performance.

If you change the theme to Windows 7 Basic, you will no longer get the full Aero experience. Aero is the premium visual experience in this version of Windows. It features a transparent glass design, window animations, Aero Flip 3D, and live window previews.

To change the theme

  1. Open Personalization by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type personalization, and then click Personalization.

  2. Under Basic and High Contrast Themes, click Windows 7 Basic or one of the High Contrast themes.
