Gosh trying to find the Open PDFs by default using anything other than Edge was a HUGE pain at work where I have to use Microsoft Shit...
It's nowhere in the settings, Edge straight up ignores the fact you set up a different PDF viewer app as a default, which takes way longer to load files than my other installed PDF readers.
You have to right click and have this option checked, smdh.
When I made a fresh install of windows 11 a few months ago I used this tool. The readme says it works on windows 10 but Iāve never tried it myself on 10. https://github.com/LeDragoX/Win-Debloat-Tools
When I got rid of edge on windows 10 a few years ago I think I booted into a live linux USB stick and deleted or renamed the edge directory. Maybe that doesnāt quite fit the definition of uninstall but the end result was edge couldnāt run afterward which is what I wanted.
well last time i tried doing that all pdf files got borked with no way to fix the issue, on windows 11.
there used to be a semi official way to do it in win10 from 2021-2024, they broke it in January and reinstalled edge tho
