File associations of a file not being assigned to windows 10 settings

First please see my efforts:

Basically when I create a file extension of a file the system does not recognise, the above shown in the two videos / gif does not work. It does not store in the system. I have tried to reinstall Windows 10 a fresh with no such luck (using 1803 iso) either.

Is this a bug in Windows 10? Or is there some solution to fixing this, as you can see in the gif file I have done this previously with ease with a .md file.

Here is some more information about my system:

Strange!
Worked here...



Try switching the association in Settings/Apps/Default apps/File types...

Try Control Panel/file association, just type in control panel and select it.

When I tried this I get the following:

It just stays like this forever, even after restarting my PC.

Specifically I clicked:

Are you using the exact same version of windows as me? Which is:

Windows 10 Home
1803
30/04/2018
17134.320

I tried to switch them out like this, also did the same on a fresh install of the following on a different system:

Windows 10 Education
1803
30/04/2018
17134.320


I have also tried it with different applications and different file extensions with the same result.

This has now been fixed when I updated to windows 10 1809 which came out a few hours after I made this post.

Mark this as Solved.

I hate to burst your Win10 v1809 bubble but the file association problem is not fixed in 1809...yet.
