[Zope] Uninstall on WinNT and the Registry

I was just uninstalling Zope 2.2b1 from a WinNT box, and selected the custom uninstall to see what all it was taking out - and when it got to the part about removing registry keys, it showed some things that looked pretty dodgy.. The dialog box legend says: "The following Registration Database Keys were created during the installation. Select those keys that you want to remove." And then goes on to list quite a few Zope-related things that sound ok, but also lists: SYSTEM SYSTEM\CurrentControlSet SYSTEM\CurrentControlSet\Services That can't be right. If the uninstall really did blow away those parts of the registry tree..you'd be screwed. What's going on here? Barry
