Windows 7 will have 5 editions coming out this fall. I haven't used the RC of Windows 7 yet (Still using XP, but I've heard good reviews of W7). I know that on June 1st, 2010, the RC will expire and you'll have to purchase a retail copy of Windows 7 otherwise the computer will shut down every 2 hours. So, when that comes (or even prior to that) can you directly UPGRADE the RC to the retail without losing your files, or do you have to do a clean installation to do that?

(P.S. I'm just curious because I'm very intrigued by Windows 7 and I'm interested in the release candidate version that came out)
