XP Activation Problem

I bought two computers, used, to give to my grandsons. Both have Windows XP Pro as the operating system.
I got them home and attempted to log on and got the msg that I must activate Windows XP and asked if I wished to do so. Answering "YES" the next screen says "Windows has already been activated" and tells me to click OK to exit. I do so and I am right back at the log in screen and the whole thing starts over again. I tried the laptop and exactly the same thing happens, what is my remedy?

 

You should contact the person or business you purchased the computers at and see if they have the orginal installation disk with the product keys for these computers. Microsoft is very miserly with Win XP. If these copies weren't registered right or the product key's weren't entered then you might end up have to spend money getting new disks and/or product key's. Also as them if they set up a log in and password and what that info is. They may have some of there personnal settings still in place blocking other people from logging on.

Then again someone here may come up with a software fix for you. Keep us posted as to what you find out and check back in case someone else has an answer.
