I haven't upgraded to 7 yet. I've had a couple of problems recently with unsolicited "antivirus" type software trying to take over my systems. I thought I'd never get rid of one of them. Also one of the Windows updates for Vista (I think) screwed up my network settings. This is the second time that has happened. The first time it took out my wireless adapter settings. On the Vista front I haven't had any more problems since turning the updates off.
