U could look for the program that does the key check, it's probably an update that has been installed automatically. Find it, uninstall it and then try again. There is no other solution but to get rid of that program. It's called genuine advantage... something

There are two primary ways to install XP.  You can do a full install which completely wipes out your hard drive, or you can do a Repair Install.  A Repair Install will NOT erase your programs or change your personal settings.  You will have to visit the Windows Update site to reinstall any updates that came out after your XP install disk was made (including SP2 if it's not on the disk.)\n\nThis link give you step by step instructions for a Repair Install, including actual screen shots of what you will see. I selected XP Pro but the steps are the same for XP Home.  I'd suggest trying the Repair Install first.  It takes about an hour.  The Windows Updates will take about another hour.  If the problems are fixed, great.  A full install takes about the same amount of time, but then you've got to reload all your other programs and put your personal settings back the way they were.  And that could take all day.  Hope this helps.\n\nhttp://www.windowsxpprofessional.windowsreinstall.com/installxpcdrepair/indexfullpage.htm\n\nplrr

Many ways! Depends on your flavour! You can simply put the XP cd in and do a fresh install over win2k, you can buy a second hard drive and install XP on it and run two seperate operating systems (my favorite)!

Well, run the windows XP setup from Windows 2000 and when you're prompted whether to upgrade or new installation, select "new installation" and chose the drive letter in a further step. There you go. Windows XP + Windows 2000 Pro

to do this legally, you need to purchase an additional upgrade licence from microsoft.\n\nif you dont care about the legality, u need an XP home Cd and install key. Just pop the cd in the drive and let it auto run.

You don't have to install windows XP again, just go to your control panel and on the left hand-side you will find windows update click on it and it will take you the windows update site, it then will automatically scan your computer for updates, download and install them, you should find SP2 as one of them.\nAnother option is to go directly to\nhttp://update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us\nWhich should work the same.
