windows 10 photos will not let me change default

I tried it on mine. If you go to file explorer and right click on photo and choose "open with", then click choose another app, a listing of apps comes up. go to the bottom of the box (not visible on mine until I arrow down to the bottom) and click "more apps" that allows you to see that Media Player is listed and a box that allows you to set it as default.

You can download .reg file and just activate it.

not the case every time. some of us have already used the .reg file to no avail. it i broken for some of us. rightclick image, click more apps, select windows photo viewer, check always use, opens image in wpv, close wpv normal click the image and it's back to being opened with photos.
