I realised only late in the day that Virtual PC (a free download here) is not intended to run on Vista Home Premium (I say intened because my version did, but the XP OS never appeared). This is a bit of shame because otherwise my home premium version is great. I like the idea of having a Virtual PC for trying something out or for browsing the net when you don't trust the other party.

Incidentally the new Microsoft Web site really is refreshing.
