Installing WinXP Home over WinXP Pro

[Dagney]

As mentioned in my previous thread, I'm in the process of backing up a computer to prepare to remove a pirate copy of WinXP Pro and install a legal copy of WinXP home.

Is this even possible? To me, it's a step backwards in the software and will leave unregistered components on the machine (which is going to be a bigger headache than I can even fathom wanting to deal with). I've thought about dropping the install disk in the (working) CD drive and letting it auto run and doing an 'upgrade' when prompted, rather than doing a clean wipe and reinstall. However, I'm not quite sure how well that will work.

Has anyone had any experience or heard any thing at all about how this works, if it works, or if I'm just too insane to even bother trying?

(No comments on the insanity, I know I'm crazy, but hey, at least I'm medicated *G*)

Danke!
