I had a similar issue.  It seems that some updates do not complete successfully under the circumstances you describe.  I 
suspect there is an issue with shells failing to run successfully as I often have to try several times before I can get 
Cygwin to open a bash shell successfully.  Others require a reboot (and you need to watch the messages for this 
information).

I found I could fix most problems by booting to safe with networking mode and reinstalling the packages that weren't 
working.  This restored my applications.  I hope this works for you as well.  I do the safe mode to prevent any problems 
with deamons or other applications running in the background.

Sincerely,

Brian S. Wilson
