I'm using my Boot Camped Windows for Parallels. My question is, if Parallels is updated so I have to reinstall Parallels on my MBP, does that basically reset my virtual machine, causing me to have to reactivate Vista on my VM? For that matter, suppose I decide I don't like Parallels, and want to switch to VMWare Fusion. Do I have to reactivate Windows on Fusion, even though I've already activated it once on Parallels? Or does Vista consider itself to still be running on the same machine as it was originally installed on? Thanks.
