@kettch: no, obviously no, because Vista runs on a new driver model which caused a lot of driver issues. And win7 used the same driver model after OEM was able to address all the issues during Vista time. I have yet to hear them doing such major change that would affect graphics or the environment that runs VS. even if the emulation is slow, as warren suggested, it is still useable, not like black screen or dead pixels or random color popping out.
