Of course, this is for those that do not have the Home Edition of Windows-XP. The Microsoft Virtual PC 2004 Service Pack 1 basically only runs on the following systems: ? Windows 2000 Professional SP4 ? Windows XP Professional or later ? Windows XP Tablet PC Edition or later.

Yes, I noticed this also. However, somebody on their newsgroup says that it works fine on XP Home, it just isn't officially supported. By the way, there is lots of useful info on the Virtual PC Newsgroup. Just click the link on Microsoft's Virtual PC home page. Nick
