Fixing Windows 7 explorer issues

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).

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.

If you have Antivirus, Update your virus definitions and try to scan your Windows 7

"Once this happened to me in Vista, and the problem was that Windows lost the EXE file association, i.e. it didn't know what to do with EXE files.

At the time this page helped me fix it: http://www.dougknox.com/xp/file_assoc.htm

Look for ""EXE File Association Fix"". It's made for Windows XP 32, and it worked for me on Vista 32, and I believe it also does on Windows 7 x64. I am on a Windows 7 x64 right now and checked some of they keys in the .reg file and it seems to have the same keys/values.

Before applying the fix, be sure do to a full registry backup, at least for HKEY_CLASSES_ROOT."
