Question

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)?

Answer 1

Try running System File Checker. Hit Win+R and type sfc /scannow and enter. This will take a while, when it's done, restart your computer.

Answer 2

OK.. this is really weird!

Please try to start your computer in the Diagnostic Startup (see http://www.freebits.co.uk/cleanboot.html for a howto). Are these issues still there in the Diagnostic Startup?

Also it can help to see in the windows-logs. To see them, open press Win+R, enter eventvwr.exe, and see in the windows-logs.

If you want, I can help you using TeamViewer (a free for personal-use remote desktop-software).
