Although you can get it to run on older hardware, with the lack of WDDM drivers available, it is going to run very slowly.

Vista Glass look on Unsupported Video Cards

This new user interface engine greatly enhances the look by utilizing several cool looking 3D effects.  Of course, to be able to fully utilize the new engine you need a good 3D video card on top of special drivers, WDDM (Windows Display Driver Model).

To turn on this effect just execute c:\Windows\System32\UXSS.exe or enable and start the User Experience Session Management Service.

1. Open up Regedit.
2. Navigate through HKEY_local_machine, Software, and Microsoft.
3. Create a new KEY called DWM.
4. In the new DWM key you created, create a DWORD called EnableMachineCheck.
5. Make sure this value is set to 0 and hardware checking is now disabled.
