What kind of problem is it giving you?
I know if you remove all the "HIDE"'s out of the sysoc.inf, it messes up.. But XP Pro has always done that...
The ones you need to leave "HIDE" in are as follows:
TerminalServer, msmsgs, TabletPC, netfx
If I leave those, my Add/Remove Programs-> Windows Comp. is just fine. If I remove them, I have messed up checkboxes without any text next to them, and the checks cannot be removed.
Hey, hope that helps.. =]
