OK, so here is the problem I'm hoping you guys can help me fix. On my Win7-Ult64 box, my explorer (among other things) has decided not to work. For example, if I try to use a program, say Chrome, to open a folder, I will get the message "Class not registered" (and its not program specific).

In the same vein, when I go to Start->Rclick Computer->properties, nothing happens, but I can go to control panel->system properties and it will work. And other items in the control panel do nothing when I click them (and I have a feeling it is all tied together).

I have already done multiple virus and spyware sweeps, so I know that isn't the problem. Any suggestions on what could be causing this/how to fix it (short of nuke and boot)?
