want to change xp corp to retail or oem

[diverdaves]

Hello  I have some xp corp installs that work but wont load optional updates because of windows sp2 wga.  I have legit XP Pro Upgrade CDs and OEM CD's, how can I convert or upgrade an existing corp install to a legit XP oem or XP retail?

Thanx

Was there ever an answer to this?

I basically did what everybody else did.  Used the corp version till I had the extra cash to get legal.  

So now I got a legal key off a new copy of XP pro sp2 that I bought at retail.  But I don't want to re-install just to get this new key loaded.  I tried magic jelly bean with no luck.

Any other ways out there?

P.S. I know I can get around all the updates by modding files.  But if I am gonna be legit I shouldn't need to get around them.
