Windows 10: can't set default apps

Hi, I just did a clean install of windows 10 on both my pc and laptop (downloaded the install tool, it installed 1803, not 1809, winver says compile 17134.376) and now I can't set default apps on both machines. nothing happens if I click a file and choose "open with" and select a different app and try setting it as default, nothing changes. to be honest, if I select an app that was already installed with windows it works, let's say I open an mp4 file with the default movies and tv app, and then I try to change the default app to say windows media player, it does change. but if I try any other software I installed, like mpc or vlc, it doesn't work. the same happens to all kinds of files and all apps that were not pre installed.


so the same happens to jpg files, if I set paint 3d as default app it works, but if I set like photoshop it doesn't.


I tried some suggestions I found online, but nothing works. what can I do? I really don't want to reinstall windows again.

Lost default photo viewer after profile rebuild


Thanks Brink. I've tried those steps before i started searching Google. After the profile rebuild i don't have the Photo app listed to choose to make it default in either the system settings for default apps or the Open With option.

I can't even find it doing a search. Seems to have been removed somehow with the profile rebuild, which doesn't make sense.

Might be helpful to list what i've done I've done the open with check, the choose default program in the system menu, tried that in device manager default programs also. I've checked the programs and features Turn windows features on/off and it's not listed there (never thought it was but that was a suggestion), searched the MS Store, it's not listed there either.

I don't like playing in the registry unless i have defined steps and haven't found anything for this yet, just the Win7 version like in my OP.
