When I got my new iMac a few months ago, I set up Boot Camp to split the disk into two. I bought and installed a copy of Windows 7 using Boot Camp. Everything worked great.

I recently bought and installed Parallels 6 and set up a VM to use my existing Boot Camp partition.

When I boot into Windows 7 from Parallels, Windows gripes about activation and has given me 3 days to activate it within Parallels.

If I activate Windows 7 from within Parallels, will that kill the activation when I boot into Windows 7 using Boot Camp?

I had absolutely no issues with Windows XP on Boot Camp/VMware, but this VMware KB article mentions that you might need two keys. This thread suggests there are problems using Windows 7 with Boot Camp/Parallels. As I'm not 100% sure on this, I post as comment, as it might help nonetheless – Daniel Beck Dec 10 '10 at 5:43

Two different machines (Not at the same time):

Parallels 6 + Snow Leopard = No
Parallels 7 + Lion = No
