Old Office Registry Keys

[dewey3k]

Hi,

I have a Dell Latitude laptop running win2k. I started with Office 2000
but have upgraded to Office XP(2002). I noticed that in the registry
under HKCU\Software\Microsoft\Office there are entries for versions
10.0 and 9.0. It seems that all the branches and entries are identical
(as near as I can tell) so my question is this: Do I need both sets of
keys/values? Or can I dump the entire 9.0 branch? There is also an 8.0
branch with an "Outlook" subkey but the only value there is "First-Run
REG_SZ False" which seems to me to be superfluous but also not terribly
annoying.

So I exported the entire 9.0 branch under
HKCU\Software\Microsoft\Office as well as
HKLM\Software\Microsoft\Office. I then deleted those branches. Nothing
seems amiss. Should I be worried?

Thanks,
Dewey.
