(It would be great if a sticky would be posted on Windows 7 and activation instead of the sticky about windows XP) I have windows 7 (64bit) installed under bootcamp, and I used vmware in the beginning. This didn't work as good as I hoped so I bought parallels. I imported the vmware image (maybe not a good idea?? I don't know). Anyhow, bootcamp seemed to be activated fine, but starting via parallels gave me a warning about using counterfeit software. After parallel tools was installed I called windows activation phone, and voila, the parallels version was activated. However if I now boot under bootcamp, it now says it is counterfeit!! aargh
