I'm looking for the best solution to the problems created by the command "C:\> MOVE \Windows \DummyDir" followed by a reboot. (That was not the actual cause of my problem ... I don't know what the cause was, but the symptom appeared equivalent to that MOVE statement.)
I started by trying "C:\> MOVE \DummyDir\Windows \Windows" but that gave me some "access" error and wouldn't work. So then I did "C:\> XCOPY/s \DummyDir\Windows \Windows". That did the trick, but then I got registry errors.
I tried restoring the registry from disk (DA0 to DAT), then from tape backup, but with no luck. So I ended up reloading Windows. That didn't produce satisfactory results, so I reloaded the entire Windows directory from tape backup (which gave satisfactory results).
Can anyone think of a quicker solution or explain some of my difficulties?
