Hi, we have Windows XP but everytime the Automatic upgrade trys to work it says we have an illegal copy (which may be the case, though we were assured it was legal, and it all worked fine until SP3). However, we would be quite happy at this point (having had a couple of years of problems like this now) to either upgrade to a legal copy of XP or upgrade to Vista. I'm just not sure what problems we might encounter if we try to do that from what is perceived by Microsoft to be an illegal copy. We don't want to fork out yet more money and end up with the same or worse problems. Any advice would be appreciated (we are not techies, but I can find the Any key these days!).
