    when I reboot and type %system is says its not found does that matter? It says I’m activated, but after 30 days it says I need to activate my copy when I click activate it says its already activated then logs me out when I go to log in it says that I need to activate windows xp. it goes into that loop and i’m locked out of my computer. Ideas?

    Best method I’ve seen so far on the net.

    My copy of XP IS genuine, I bought it brand new in 2002 I believe. It’s just I’ve had to do so many tweaks and re-installs that I’ve run out of tries. Never even knew that was going to happen; you’d think with a CD it’d be unlimited. SURPRISE!

    Kudos, you’ve saved my bacon!!
