Explorer Freezing and Crashing in Windows 7

I've come across this over 10 times now over the last year or so supporting about 400+ users. I'm not sure of the root cause but the behavior you will generally see is Explorer stop responding, Windows tries to find a solution in vain, and then explorer just restarts. This will occur every time you Right-Click on an explorer object such as

• The Computer option in the Start Menu
• The Taskbar
• Any File or folder
