ok guys! here's the problem: I bought a new PC, XP Pro (OEM) came installed with it. Now, i think some win files are corrupt. I didn't get a XP CD with it. But i dont have the CD-KEY!!!! I went thru the registry, got a 20 digit Product ID. CD-Key is 25 digit!! I searched the forums, and got that as the answer, but it didn't work. How do i find out my cd key for windows thats installed on my HD? BTW, windows works fine, so i can still use xp.
