no longer able to restart Windows Explorer

It's the only error that I found - your choice!

However, it may be a good idea to swap it back to the normal one, in case an update has changed something expected in that file - if your symptoms remain then at least you can rule it out as being related to the problem.

I may have to agree that the uiautomationcore32.dll is suspect, as the dwm.exe is also affected; if, in the event that system32/explorer.exe does not launch, I then try to restart the system32/dwm.exe, I am unable to restart that process, so I don't get my Windows 7 Aero theme.
