Documentation doesn't open properly?

I’m sure this is such a noob question but, when I click on the little documentation icons on the components to go straight to the manual, it opens up in notepad with just garabage letters on it. I can’t find preferences or anything to change this so it opens properly? I’m sure it’s an easy fix, thanks.

Fyi, it opens up like so:

Unity - Manual: Transform

It’s trying to open an HTML file. You need to tell Windows to use the web browser to open HTML files.

Other people have had the same issue:

Maybe this will help:

That was easy, thanks boolfone.

Just for anyone else’s reference:

If you find those documentation files in your C drive, right click on any one of them, go to properties, and change the default to open html files with internet explorer instead of notepad/notepad++.
