    How to change default app for file type

    'Open With > Choose another app' has three step, in the first it only offers apps registered for that file type. If you click 'More apps' it lists all registered apps regardless of suitability. Both these steps have the tick-box for 'Always use...' in my 18363.752. The third step, if needed, is 'Look for another app on this PC'. The 'Always use...' must be ticked before taking this step if you want the change to stick. However, WMP appears at the second step.

    For a quick look at a JPG almost anything (including WMP) is more practical than Photos which on my system takes more than ten seconds just to open a photo. The OP is probably not aware that the Windows Photo Viewer is still available in W10, but hidden away. That's my default viewer for JPG.


    Restore Windows Photo Viewer in Windows 10

    And, once enabled, is available in Settings > Apps > Default apps.

    How to change default app for file type

    @Bree - yes, I'm quite aware of this thanks, but as you will see it's missing. I recall reading that clicking the dialogue at a certain point in blank space made it appear, and trying that once successfully, but doesn't seem to help now. Plenty of other similar reports of this option being missing.

    How to change File type on Windows 10 - File Extension Change

    Windows 10

    my jpegs. open with paint. Is that normal? It was a photo and opened in paint.

    I want to see the page of all the file extensions to see what they are opening.

    Somehow my friend has changed her DIP program to opening with pngs and thy won't open at all. she needs to change them back to what they were. I have looked online anf found nothing that helps...too complicated.

    Could I please get a step by step 1, 2, 3 etc list to help her change her program extension to the right one.

    Please and thank you.
