Action

Install Windows Vista on a system with an Intel Menlow processor

Result

The performance score will report an incorrect index number for graphics, thus causing Aero to be enabled by default.

Cause

Windows Vista (including SP1 and Sp2) was developed before the Intel Menlow platform was available.   The Intel GMA500 graphics adapter in the Intel Menlow platform has a new rendering model that is not currently supported by the performance measurement tool in Windows Vista (WinSAT.EXE). 

Resolution



Manually disable Aero to improve performance by following these steps:

1. Right-Click on a blank area of desktop

2. Select Personalize from the context menu

3. Click Window Color and Appearance Option

4. Click the link near the bottom for "Open classic appearance properties for more color options"

5. Select Windows Vista Basic and click Apply and OK
