I want to sell an old pc that has Windows XP home on it registered to me. I want to un-resister it so that someone else that buys it can register it. How do I do this?

 

Although you used your name when registering it, the version of XP is registered to the COA on the computer itself. Not sure if "unregistering" is possible. It would be best to clean the "C" drive and sell it without an OS and let the new owner reinstall it using the COA. That is what I have done on several occasions.

 

Can't be done as far as I know.

I hope that you know that what you had on the hard drive is never really deleted even if you reformat and reinstall windows..
Most people I know will remove the hard drive before selling which would contain private info and let the new owner install a new hard drive.

You might be able to replace the hard drive and reinstall your ver of windows.
The information that would still be on your old hard drive would be more of a concern that it being registered in your name.
What harm would come of that?

 

I have run various eraser programs to wipe it. So far, the one I used last seems to work just fine. I can't recover anything. The reason I may not yank the drive, is that I think having Windows XP on it may be the best selling point. I have thought of yanking the drive and selling the XP software along with the teh computer sans hdd. I don't know if I can get as much for it.

As it stands, even with a working hdd I may only get 150-200 for it.(if I am lucky)

 

I think if it were me selling the computer then I would just include the Windows XP disk with the computer and sell the computer and the software together. Windows XP is about to be retired by Microsoft anyway since now there is Windows 7 and for the most part doesn't have as many complaints as Vista had. I did hear they would continue support for Windows XP a bit longer for laptops than for desktops. I guess Microsoft scans the computer and that is how they know what you have.If you want to use the operating system again why not download Linux and install that or if you don't have a high speed connection I have seen it real cheap on e-bay. I have never used Linux but there are those who really swear by it and say it is better. As for drivers though for some things well not all manufacturers support Linux so investigation is warranted. If the drivers are available then I would buy it if I had too as you can use it over and over again. Good luck to you!

 

Command "del C:" to wipe the hard drive. Then copy the XP disk but don't include the product key.

I use Linux and enjoy it!

 

What good is the XP disk without the registration key?

 

Isn't that what he's trying to do?
