I recently upgraded my main home machine from WinXP Home to Pro. This leaves my XP Home version eligible to install on my secondary machine which currently has Win98SE on it. Question is, how do I "deactivate" the activation for the computer XP Home was on so I can apply the activcation to the second machine since MS will reject the attempt to activate XP on the second machine due to different hardware, etc. Is there a procedure for this? Does MS have to be contacted, etc.?

Thanks,
Bill
