How do I restore my computer back to Windows XP?


I have my nephews my old desktop computer, which had Windows XP on it.
However, someone put a Windows 2000 disk in (just see what it was – I guess)
and now the OS is Windows ME. Is there any way to restore that computer back to


I say that because there’s no way that putting a Windows 2000 disk into a
machine is going to result in that machine running Windows Me.
And installing an operating system – ME, 2000 or even XP – doesn’t just happen
by accident; it requires interaction with someone who’s explicitly answering
questions about how the operating should be configured.

I’m guessing that a lot more has happened to that machine than your question
would seem to indicate.

“Restoring” to Windows XP could mean several things.

If you’re just looking to get XP onto the machine and there’s no data to be
preserved, then the best solution is to get the original Windows XP
installation CD that hopefully came with the machine and simply reinstall
Windows XP from scratch. If there really is no data to be preserved, then I’d
strongly recommend having Windows XP Setup reformat the hard drive in the
process so as to have a completely clean machine running Windows XP.

I have an overview of setting up a machine simply in this previous article:
How do I set up my computer
– simply?

If you’re wanting to restore the machine to it’s previous state,
which means more than just the operating system but includes applications and
data as well, things are much more difficult.

You probably don’t have it, but I’ll say it anyway to point out how useful
it would have been: if you’d been using a backup program to backup the entire
machine, you could simply restore to the most recent backup made prior to
losing Windows XP. Most backup programs actually make this quite easy albeit a
little time consuming. And the net result is that you would have had the
machine back exactly as it was at the time of the backup.

Given how invasive a new operating system installation is, your chances of
actually getting back to what you had before by “undoing” the operating system
installs is pretty much zero. Honestly, an installation of Windows XP from
scratch or a restore from backup are by far your best bets.

If you can’t take those paths then here are two more straws to grasp at:

  • Upgrade Install – rather than a full format-the-hard-disk
    install, use your Windows XP CD to install and “upgrade” the machine from
    Windows Me. This should preserve most of the machine’s settings and
    your data. But I’d be sure to so a back up first just in case.

  • Use Dual Boot – you didn’t mention it, so I’ll assume it’s
    not there. There’s a small possibility that your Windows XP installation is
    still there. If when you boot you get the option to choose your
    operating system and Windows XP is listed, then you may be able to simply remove
    the other choices. Normally I’d then also tell you that you could go and delete
    the folders or partitions that might represent the other operating system(s),
    but in all honesty given what your system has been through I’d be too concerned
    about accidentally erasing something important.

Even if either of these approaches succeed, I still believe strongly that
you should then backup any data you want to preserve and reinstall Windows XP
from scratch. It’ll give you the cleanest, most stable result.

  1. If a Windows Me desktop is upgraded to Windows XP,
    which is what I suspect happened to this old computer,
    a backup is automatically taken of the old installation so
    that the user can go back if the Windows XP upgrade fails.

    I imagine this mandatory backup was never
    deleted on the computer and the Windows
    2000 installation failed as it would trying
    to go ever XP which cannot be done.
    The machine rolled back to Me.

    The best solution is to upgrade the Windows
    Me with Windows XP as was done originally.

  2. I cannot believe you would include this message in your website, but I applaud your desire to help even the most incredibly mixed up computer user.

    I hope this person can comprehend the need for, and the mechanical methods of, backing up their important data. ‘Cause it ain’t gonna get any better anytime soon. This person is computer illiterate. Their data is in extreme danger.

    God bless ’em.

  3. Milk – That’s the point of Leos site… to educate. Even those of us who’ve been using Windows for decades still started out somewhere knowing absolutely nothing. Not one of us is born “computer literate.”

    New generations of newbies crop up and they, too, must be taken by the hand and led along until they can walk with the elders. They need info and knowledge, not disdain and contempt.

  4. I have my installation disk for windows Xp, but
    they ask me for my confirmation number before I can install it, which Im can’t find. what do I do now?

    Thank you

  5. I have been using windows XP backup for years now and have never needed it until yesterday. My hard drive failed so after it was replaced, I went to restore my system using windows backup’s restore function. First I have it stall windows to get to my WD usb drive. Them after 38 hours of restoring, I find that none of my programs will run because they are not registered and I and instructed to reinstall them. Is there a way to get these programs to run without going through the re-installation process?
