Accidentally denied my regular user account access to "Network" dir.

I have a computer running windows 7 64bit ult. I changed settings on the Network-PC\users\BOB to deny all access to BOB. Immediately after doing this my desktop disappeared and things stopped working. I thought it was a simple fix.

I went into the Admin account and changed it so that user BOB had access to the directory BOB. As far as I can tell, I've given BOB every possible ability to access anything. However, logging into BOB results in the inability to use windows search, unable to open video files in %appdata%, almost every program is broken either saying corruption (which isn't true) or out of memory or access denied.

I attempted to create a new username but certain programs will not open under this username. Is there ANY way to simply UNDO that one step. According to admin and everything BOB should have unrestricted access to everything but everything is broken. Could not even get simple things to run like Handbrake.

All permissions on every drive is set to allow BOB full control. Attempting to set permissions within the account called BOB results in the false error message that the file doesn't exist or BOB doesn't have access. Right click shows full access.

I need to figure out how to undo ONE mistake, you'd think it would be as easy as undoing what you did but apparently windows error messages are generating errors that are themselves: errors. I've tried adjusting "owners" but that is practically a field of quantum physics. Ran SFC /scannow as suggested elsewhere and nothing.

EDIT: Addition:
Trying to access certain files while on the ADMIN profile results in an error message that says "\BOB\Programnamehere\ refers to a location that is unavailable."

I just need to unbreak every single program on my computer.

Try a System Restore from before the issue - http://www.sevenforums.com/tutorials/700-system-restore.html

If this fails, right click the user folder for problem account - properties - security - advanced - owner - edit - select the account and make sure checkbox is ticked (replace owner on subco...).

Also add administrator as full control for where you get those "location unavailable" warnings.
