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.

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 remove a default file association app from a file type in Windows 10 - set to "no default app" associated

Hi Goa,

When you selected a certain program in “Open With” there is no option to revert this change. Since DLL files are independent, there is no other program than you can replace the default program with it.
To help you out with your concerns with default programs, we'd like to ask you some questions:

• What were the recent changes made on your computer before you experienced this issue?
• What are the workarounds you have done so far?

• Have you assigned Excel as a default program for DLL files? We would like to confirm this.

You can navigate this by following the steps on this link:
Change default programs in Windows 10. Once there, click
Open Default apps. Then, click Choose default apps by file type.
Look for the DLL file, see if you can remove the assigned program in the DLL format.

Your response will be much appreciated.
