You could try the dll Application reset under Option Two - To Restore Specific File Type or Protocol Association to Default in the following link:

As a general precaution create a System Restore Point beforehand and restart the computer afterwards.

Hi Dollar20USA

It does not really matter if dll file associations have been set to Notepad, your PC will still continue to function asnormal

However, if you do want to break that file association:

Open Windows File Explorer

On the view Ribbon (tab) check the box marked 'File Name Extensions'

Close File Explorer

Right click your Desktop and choose New - Text File

Change the file extension on that new file from .txt to .exe

Confirm the change

Right click a .dll file, choose open with - Choose another App

Check the box marked 'Always use this app to open .dll files' - IMPORTANT!

Scroll to the bottom and click 'More Apps'

Again scroll to the bottom and choose 'Find another app on this PC'

Navigate to the dummy file exe on your Desktop and click OK

The .dll file will not open

Delete the dummy exe file on your Desktop and restart your PC

The file association will then be broken!
