a friend of mine was given a comp with windows xp on it and then they installed windows xp upgrade. how do I remove the upgrade or do I need to wipe the whole C drive clean as it is taking up a lot of memory and a lot of the programs are interferring with each other.

IF an upgrade goes wrong, formatting the drive is probably the best thing to do. However, if you want to try and uninstall here is a site with instructions:
uninstall upgrades

The best thing to do is format and install the OS best suited for that computer .

I don't have the CD to reinstall Window's XP so how can I reformat? It is a Dell Computer.

Thanks in advance
