ok here is what i ment. My friend gave me a clean new never used windows XP pro. The problem was that it was from dell. The PIN (when you install windows and you have 30 days to activate windows) didn't want to work, so I got a new CD, and since I alread had all these programs installed, I don't want to lose them. I herd it's called upgrading, but when I insert the CD in the drive and click Install windows XP it says that there is a newer version installed and that I have to boot from CD. When I go there I don't see any option of upgrading. I see overwriting, but not upgrading. And my question was, can I upgrade the new CD without loosing and programs.
