I've been getting this message every day that my windows 7 is going to expire. I thought I had an RTM build of it, and it's been activated with windows-loader, but now I've gotten this all of the sudden. It's down to 10 days, so I'm starting to worry. I can't get it to pop up now, but it basically says "Back up important data, you are running a prerelease version of windows 7 and it will expire in 10 days. I think I might've installed a prerelease of SP1, so maybe that's causing it? IDK..I just want it fixed!
