Helping people with computers... one answer at a time.
You can't remove a Windows operating system, but it is possible (and good practice) to reformat a hard drive and reinstall from scratch.
I have a rebuilt PC. I had Windows XP on it. An idiot put non-genuine Windows 7 on it. How do I undo this mess? I do have an installation disc for Windows XP, but no CD for Windows 7. Is it possible to uninstall or delete Windows 7 and reinstall Windows XP on my PC? Thanks for any help.
In this excerpt from Answercast #34, I look at the steps necessary to revert a computer that has been upgraded to Windows 7 back to XP.
So absolutely. Sure, you can do that. Especially since you have the installation media for Windows XP.
It may be helpful to erase the hard disk first; and it may be safer to backup your hard disk first to make sure you don't lose anything that happens to be important to you on that Windows 7 system.
After backing up, erase it with a tool like DBan;
Then boot from the Windows XP installation disc;
And you should be able to install Windows XP from scratch.
At that point, you would simply go ahead and
Reinstall the applications you care about;
and you should be good to go.
