Fix Aero Glass on Low end DX9 Cards
Some people with low end DX9 cards (Geforce 5×00 series and ATI 9×00 series) have been reporting issues of Aero Glass not enabling itself despite getting a system rating more than good enough to run Aero Glass. This is a known issue in RC2 and is on the board to be fixed in RTM. But for now here's the workaround that I spotted on AeroXP (Posted by Colonel.Cool).
1. Ensure that you have the following registry value set to :
HKCU\Software\Microsoft\Windows\DWM\Composition set to 1 (32-bit DWORD)
HKCU\Software\Microsoft\Windows\DWM\CompositionPolicy set to 2 (32-bit DWORD)
2. Restart DWM by opening a command prompt with administrative privileges :
- Type 'net stop uxsms'
- Then 'net start uxsms'
After doing this you should have Glass, enjoy!
NOTE: Do NOT try this on a non-DX9 card. This is for people who should be getting Glass only.
simplifié en francais :
pour une carte graphique supportant dirext X 9 (même pas puissante), activation d'aero sous vista :
regedit –>
HKCU\Software\Microsoft\Windows\DWM\Composition = 1
HKCU\Software\Microsoft\Windows\DWM\CompositionPolicy = 2
redémarrer
