I am getting the following message box when I boot up the computer.

Message: Since windows was first installed on this computer the hardware has
changed significantly. Due to these changes windows needs to be reacatived
within 3 days.
Yes
No

This started yesterday evening. There have been no hardware changes to the
computer of any kind since it was purchased from Dell. It has xp home
edition.

Can anyone tell me what could be causing this? Is it a problem in the
service program, or udate program?

Thanks,

Bob Sellers
