I've just gone through the process of rolling back all of the Windows updates that I was able to, which means all of the Windows-specific ones, but only some of the Office updates. Some Office updates could not be uninstalled.
When I couldn't reverse the Office updates, I tried to do a System Restore back to the day before updates. System Restore said that it hadn't actually changed anything, and when I checked, the Office updates were still there.
I then uninstalled the updated HTC Sync software (which I didn't expect to be the issue), and installed my original version of HTC Sync. That also made no difference.
So the outcome is: I still can't sync my contacts with Outlook, which is causing real problems. Next step will be to try it on a Vista PC, but that isn't a solution, since I rarely use that machine.
