-Windows XP came preinstalled on my computer. I tried to reinstall windows xp before but I couldn't because I didn't have a product key. Do I need one for this method and where would I get the product key if I do: How-to repair Windows XP, How to Perform an In-Place Upgrade http://www.geekstogo...ws_XP-t138.html
-Also, I thought you could lose data/programs when doing this if windows came preinstalled on the computer? I know I saw something about that on the Microsoft website before.
-One more thing, how do I do this: Step 2: Backup. It's always a good idea to backup your important data before making changes to Windows XP. Relax, if you follow these instructions your data will be perfectly safe. Metallica said something about maybe being able to use the SP2 CD as a backup.
