I have a new system I'm building up with the 120 day Business evaluation kit, XP Pro which is good for 120 days. It llooks good and I want to keep it, what do I do to keep the system going after the 120 days are up? Can I purchase the Upgrade version or do I need a full or OEM version to activate it forever? Also, I have the office XP 30 day installed and it won't take service packs or download updates. Any reason for this? Thanks! Clark CWNicholls@aol.com
