Specs: Windows XP
How can I go from XP professional to XP home edition? I bought a PC from someone and have been using it for sometime. Now I am getting invalid version messages from Microsoft. I have a valid copy of XP home. Can I load that without having to offload and reload all my files?

What "invalid version" messages are you getting? Have you activated the OS?

What are you doing when you get those messages?
Post the exact message.

"Can I load that without having to offload and reload all my files?"
Sorry no. You will have to format the drive to install XP Home. But there are ways to copy files off the drive, before you format.

Are you trying to go backwards cause you won't be able to do that. You'll have to do a fresh install.

Thanks for the reply's.
The message I get from Microsoft is :
"You may be the victim of software counterfeiting. This copy of windows did not pass genuine windows validation."
Which started after a reboot, it appears above the task bar and there is a blue star on the task reporting the same message.

If you're getting that message, then XP hasn't been activated, or the activation code was disabled by Microsoft. Contact them.

Presumably too... you have managed to acquitre/save data to the hard-drive? Before you set abut (re-)installing "any" OS.. boot up with a Knoppix/Ubuntu disk (whichever) and copy your data to optical media; and verify the copies will read etc. on at least one other system.. That way regardless of how you go about getting a working OS... your data is safe off the system as is...

If you go to installing Home Edition... no need to reformat etc... Simply (a fresh) install it alongside the current Pro version - and in its own folder...

You will have a dual boot scenario; the boot.ini/menu will list both versions. The last one in is always set as default OS to boot. The Pro Edtion will be listed below it in the main list; and if it won't work (no-longer activated etc...?) then simply locate that Pro Edition) folder on the drive and delete it. Do this via Explorer in Home when booted up etc... Pro folder name will be clearly stated in its entry within the boot.ini; and will be different to that for Home edition...

Then edit boot.ini to remove line for Pro Edition.

The "default OS to boot" line will be duplicated immediately below that statement; note it carefully - and ensure you delete the other line (which refers to Pro).

Again - "before" you install any futher OS - safeguard data as above... Once you have a working OS again - copy data back to drive - if it by chance has been erased during setup of Home or whichever OS...

It may be a crooked version but it has been activated.

You must use ntbackup to save data then install xp home and install ntbackup and restore.
