Re: Fastest?Easiest Win 7 Upgrade from Win RC (have XP and Vista Upgrade DVD)
Nope I didn't have to try any trick, I just inserted the dvd while in Windows and followed the prompts and that was it.
If it does deactivate the cd key for your previous OS then get the Win 7 RC now while it's available, install it then upgrade to the final version then burn an image of the drive like I did.
If you ever need to restore it, then you just boot up with the Win 7 upgrade cd, then choose repair and restore image, no having to mess with anymore cd key or anything. I saved my image on the other hard drive in my computer. I'll burn a copy on a couple dvds later.
