Notes:

- Open up your steamapps folder
- Look for the Skyrim App Manifest (489830 for Skyrim SE, which is what most people play, if not look up the appmanifest for your version of skyrim, be it oldrim, LE or what have you)
- Right click on the appmanifest file
- Select Properties
- Check the "read only" dialogue box
- Click apply and OK

Now Todd's updates can never reach your game and f--- everything up ever again.
You're welcome
