I think I fixed it. I went to "Apps and Features", found Microsoft Photos, clicked on the hamburger menu on the far right, chose "advanced options" went to the Reset section and performed both the Repair and the Reset functions. After that I was then able to associate jpg and other file types to Irfanview.
Widows 11 setting default program for jpg files is not working
Just installed W11, clean install. I installed Irfanview for my image viewer and simple editing. However it will not associate jpg and png file types, although it did for many other file types. I tried installing as an Administrator. I tried setting associations from within Irfanview. I tried going to the Default Programs control panel and tried to associate jpg files with Irfanview. JPG is not listed in the file types. Nore is png. Both have been taken by Photo Viewer and nothing seems to make it give it up.
I understand that VLC video viewer is also having trouble with setting file associations.
I am using the 64 bit version of Irfanview, latest version. I am using Windows 11 Home.

I am Dave, I will help you with this.
Open IrfanView, and open Task Manager, then select the Processes tab
Find IrfanView on the Processes tab. right click that and choose Open File Location
Note down the location of the IrfanView executable
Right click any JPG file and select Properties
Click the 'Change' button on the resulting dialog.
Then navigate through the resulting menus until you get to choose to find the app yourself and navigate to find the IrfanView executable you noted down earlier
Save that setting.
