Since a few weeks Microsoft Edge keeps hijacking my .pdf and .htm files.
My choices for opening these files are Adobe Acrobat Reader DC and Firefox respectively. I can change the settings so that .pdf and .htm opens in these apps (aka my favorite apps), but the change doesn't last. Microsoft Edge hijacks them back after a day or two.
Every time Microsoft Edge hijacks .pdf and .htm I try one, two or all of the following settings changes:
a) Right click on the file and select Properties => Opens with => Change => select the app I prefer. Then press Apply and OK.
b) Right click on the file and select Open With => Choose Another App => Select the app I prefer. Tick the box "Always use this app to open..." . The press OK.
c) Press "Start" => Settings => "Choose a default app for each type of file" => navigate to .pdf and .htm respectively to select the app I prefer.
Everything seems fine a day or two, .pdf files keeps opening in Adobe Acrobat and .htm files keep opening in Firefox, but then suddenly BANG! Microsoft Edge has hijact .pdf and .htm AGAIN!
This drives me nuts! I have Googled this issue over and over again, and the only advice I haven't tested yet is related to Registry changes.
I don't want to modify the Registry. This seems stupid and dangerous!
I use Windows 10 Pro version 1511, 64 bit
The OS Build is 10586.633.
Microsoft Edge is 25.10586.0.0
Any help appreciated!
