By turning off the background extensions "acrobat elements context Menu", and "Adobe Drive CS4" using ShellEXview (64)... I was able to fix not only "Zip" files crashing, but "File Explorer" crashing when started from the toolbar. I also think Illustrator CS4 not starting may have been related to this conflict.
All were terrible bugs to my productivity, and really should have been addressed by Windows Support a year ago when an update seemed to create the conflict. Not since Windows 8 have I had such a poor product experience.
