Reverting to XP Home


J

Jerry

I purchased a computer which had xp home pre installed. Recently a
"friend" upgraded me to pro whilst fitting me some more memory and a
new graphics card, but since a recent update it shows that it has an
invalid registration. Can I revert back to my original home
installation without losing all my data, bearing in mind I have
upgraded some hardware?

Not that I know of, unless you see an uninstall option in Add/Remove
Programs (and I'm not sure whether you will see this in a Home-->Pro
upgrade; I've rarely done those).
Do you have the original installation media?
I would probably just back up the data and reinstall from scratch....or get
this "friend" to pony up the cash so you can buy a valid copy of Pro. :)

Hi

If you want to revert to Home, you will have to perform a 'Clean' install of
XP which delete everything on the hard disk/partition. If you do want to go
that way, then you will need to backup all your valuable data files for
future use. Any programs/apps that you have installed will, however be
lost.

The only way to change from WinXP Pro to WinXP Home is to
format the drive and start over. There is no supported downgrade path
or technique.

Simply boot from the WinXP Home installation CD. You'll be
offered the opportunity to delete, create, and format partitions as
part of the installation process. (You may need to re-arrange the
order of boot devices in the PC's BIOS to boot from the CD.)

Unfortunately there is no downgrade path from Pro to Home. To do this
requires a clean install. Backup all data. Make sure you have the
original media to reinstall all programs.

See this link for how to do a clean install.

Your "friend" has ruined your computer.

Easiest thing to do is buy a copy of XP-Pro and get legal. Shouldn't cost
more than a couple of hundred bucks which your "friend," no doubt, will
supply.
