Don't ask me why I did this, I just did
I was wondering, though. When I entered my RTM key at the end of RC setup it said that I had activated that version of windows and when I go to system is tells me it's activated. I'm still getting warnings that my OS will expire in a few hours here so it's got me worried. I'm about to put in my Windows 7 Disc and reinstall but I want to be sure that the key I have won't be invalidated because I used it on my RC.
