Explorer.exe will not open, even from Command Prompt

I have Windows Vista Home Premium. Somehow my registry got corrupted I suppose and explorer will not run.

If I double click any folder, it brings up Microsoft One Note. Same thing if I right click the task bar and click "Open Folder" - I get MS One Note. If I go to a command prompt window and go to C:\Windows and type explorer.exe, I get a message box saying "This file does not have a program associated with it. Create an association in the Set Associations Control Panel." I can't open Control Panel though, if I go to Control Panel I get the same message. I found the CP .exe files and tried opening them through a command prompt - same thing. Basically anything that uses an explorer will not open at all.

Any ideas how to fix this? I assume I need to set this association in the registry but I haven't been able to figure out where or what to set.

Thanks.

That makes no difference. I am the administrator on my machine anyway. It opens Command Prompt as administrator by default. It has nothing to do with authorities. The file association for explorer.exe is missing or set improperly.

Great, if I missed that one, it would have been strike 2. Glad it all worked out.
