So i use auto key for quickly opening up tabs in chrome, well the other day i was doing my normal routine and it loaded chrome but said it wasnt the default browser.
as odd as i thought that was i clicked 'Set as default browser'.
Well it then pops up the settings, default apps window, and i see that they are all there but my browser.
no problem right? wrong, i clicked on the 'plus' then on chrome and nothing happens, same for any other broswer.

cutting a portion of the story out i used the reset option and now windows explorer is my default (chrome still works) and all of my default apps have been changed to nothing, and like with the browser i cant change those either.

Any help is welcome, i am wondering if its a windows problem or what (yes my PC should be up to date and so should chrome).

Edit: i can provide a video if needed.
