I think this what you were talking about
http://www.vistababble.com/downloads...other-tips.pdf, page 35.
The issue has to do with Aero Glass not enabling itself even though the rating indicates that the PC should be able to run the Aero Glass. It’s supposedly a known issue with Vista RC2 and should be fixed in RTM. However, if you don’t get the RTM, there is a walk around so you can take advantage of the Aero Glass now, without waiting until January.
1. Click Start, type RegEdit and it Enter.
2. Go to HKEY_CURRENT_USER\ Software\Microsoft\Windows and click DWM
3. Double-Click Composition (right pane) and set the Value data to 1 and click OK
4. Double-Click CompositionPolicy (right pane) and set the Value data to 1 and click OK.
5. Close RegEdit.
But the key words there iare that the PC must be able to run Aero in the first place. I have not try it, so I cannot comment about it, but maybe it'll work.
