Hi all! I'm trying to find a conclusive way to determine whether or not a Win2K system has been upgraded from Win9x, preferably by either looking at a value in the registry or looking at MS Installer's files. There's a registry key named HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Win9xUpg that is on several upgraded systems that I've looked at, and is not on several fresh-install systems that I looked at, but I don't know if it's conclusive or not. Anyway, I'm asking because some systems seem to have trouble with MS Office after installing a windows service pack, and it seems to be related to upgraded systems and MSI. I'd like to be able to determine which systems I'm likely to have trouble with before installing a service pack. On the systems that are problematical, I find that I typically have to rip Office out by the roots via the msicuu and the Office removal tool. Better yet, I'd like to know if there's an easy, preferably automatable, way to prevent the problems from happening in the first place. Thanks! --Scott.
