Changing XP Product Key

By gota ·
I've created a bootable WinXP CD slipstreamed with SP2 and hotfixes from a Dell XPS400.
I've formatted and installed WinXP using the CD on a Dell Dim4400.
How do I change the XP product key to the licensed Dim4400 one?
I'm afraid to try activating/windows update on the Dim4400 in fear it will screw up my original XPS machine license.

Run Sysprep

Go ahead and do activation.
Either it will accept or not accept. If it does, you are done. If it does not, a window pops up and asks you to provide the correct Product Key.

In the future, right after the Windows installation by using the slipstreamed CD, run Sysprep (Start > Run) with the following keys.

Sysprep ?reseal ?quiet ?reboot

This will reinitialize Windows and you have to provide Product Key and others.

Sysprep is in the Windows CD (Support\Tools\
