I wanted to post that I have discovered the solution to this problem.
Somehow, a single file was deleted from my Windows directory. I don't know how, since it was a hidden file, but nevertheless it must have been deleted.
The file is
WindowsShell.Manifest, and it was located in the C:\Windows directory. I got a copy of this file from my friend's computer and put it back in my Windows directory and now I have all functioning tabs in the Display Properties dialog box. So in the future, if anyone ever has this problem, the first thing you should do is search your Windows directory for the file
WindowsShell.Manifest to see if it is missing. And remember when you look for it...
this is supposed to be a hidden file!Thanks to everyone who offered their patience and assistance. It was greatly appreciated!
