FIX: The Explorer.exe process stops responding (hangs) when you use Windows Explorer that hosts a shell extension that was created by using MFC

Right click causes explorer crash fix
A lot of people I have discovered within the last few days have had a problem with right clicking in explorer, causing it to crash. This occurs of Vista, and 7 (7100 atleast) when you install an app, and it installs a context menu shortcut or whatever.

There's actually a solution for this from MS now...

I had this problem for months and whatever I would disable it would come back after running a few days. I also had problems with the desktop not refreshing when renaming or deleting files. Nothing worked, so I eventually turned all the shell extensions back on.

One day, lo and behold, the Action Center told me there was a beta fix for it. No idea what I had to do to get it, I guess restart explorer 1000 times was the easter egg...

Anyway, the page for the fix is here, and it solved both issues for me:
