Well, I'm not sure how much I'm blaming Microsoft. So far as I can tell, it
was the Windows Update which caused the actual problem. Windows Mail was
working fine before that. And it was only after the Update that Windows Mail
stopped working.
And I have no idea why System Restore didn't work. Or why 'uninstalling'
didn't work. And though I think it is unlikely that only our computer was
affected, I didn't see anything in Windows Update about fixing the problem.
All of that is Microsoft. So I guess there's no way to do anything but blame
Microsoft. How much of it was avoidable? Or could have been more easily
fixed? I don't know.
As for anti-virus programs --- which in this case might have had nothing at
all to do with the problems --- I'm not that impressed with the results of
them so far. Once a virus managed to successfully attack our Norton expiry
date, and we couldn't get Norton to do anything about that. Another time I
found viruses would avoid the virus scanning by just jumping back to files
that had already been scanned. So, all in all, I'm NOT that impressed with
Norton. I'm also suspicious about how often Norton claims these computers
are being attacked and defended. It seems to happen an awful lot, but maybe
that's real ... I have no way of knowing.
Still viruses ARE plentiful enough that I don't think advising people to
uninstall their anti-virus program --- and I've seen that advice given on
occasion --- is very helpful.
Maybe Norton is a major culprit. But I don't know why Microsoft can't
address the false "out of memory or disk full" errors, or the "MSOE.DLL won't
initialize errors". They aren't new problems, since some of the messages I
saw about them date back to at least 2007.
Still I should note that SFC.EXE, which seems to have solved the problem,
did come from Microsoft.
Thanks again to everyone.
