Many years ago (2002) I reinstalled Windows 98 Standard Edition over top of itself. As far as I can remember, I think this was because my D:\ (CD ROM) disappeared from in My Computer and I couldn’t figure out why. Anyway, I never knew about the Version Conflict Manager until recently. The following is what it shows. In the lower table I have added a column of what versions show when I check the properties of the files that the manager shows as unknown. There you'll notice that the versions seem to be the same as the "Was" column, except for one, and that the files that were version 4.4.0.3388 now have the zero missing from the third spot. My first question is… Should I be restoring all these files to the versions I had prior to the reinstall? Also, I have Windows 98 Service Pack 1 listed in my Add/Remove Programs list. I don't remember from where or when this was installed. Should it have been reinstalled too, or was it on my 98 disk and would have been reinstalled with the rest of 98? I had the system built at a local shop and my disk is a Microsoft OEM that says "For distribution with a new PC only". If you do suggest that I restore the files and reinstall the Service Pack, which comes first?
