When I navigate to C:\Windows\System32\ and double-click on notepad.exe, it instead launches Textpad. I HATE Textpad. I want to restore the usual behaviour of loading Notepad.
The odd thing is, that notepad.exe looks like the usual Notepad that I would expect (see screenshot below). When I copy notepad.exe from another computer and paste it as "notepad-II.exe", double-clicking that opens Notepad as expected. But when I do a Beyond Compare on notepad.exe and notepad-II.exe, it says "Binary Same". However running "notepad.exe" launches Textpad, while running "notepad-II.exe" launches Notepad.
So my next step was to rename "notepad.exe" to "notepad-OLD.exe" and rename "notepad-II.exe" to "notepad.exe". No such luck, I "need permission from TrustedInstaller to perform this action", and no matter what I do from here, whether it be run as Administrator, or try and grant permission to myself, I get "Access is denied".
Help! How do I make notepad.exe launch Notepad like it is supposed to?
I am running Windows Server 2008 R2 Standard with Service Pack 1.
