I have WinXP Pro (NTFS) on my PC. I am planning to format and reinstall WinXP Pro again on it. I have WinXP Pro CD from my friend which came with some AFL (Additional Family Licence). I think it was for 10 installations as my friend said. Now he is not sure if the CD has already used in 10 installations. I downloaded WinXP from that CD about 2 years ago. Now if I start format and clean reinstall from that CD again, what if it has already finished the given number of installations as per its AFL ? I am sorry if the question is not very clear to you because even I am confused here. Thanks!
