Windows 10: Why does Windows 10 keep changing my default program for opening PDF f

Why does Windows 10 keep changing my default program for opening PDF files? It's now doing this so frequently that within moments of me setting PDF files to be opened by Adobe Reader, it's back to Edge within moments.

Equally as infuriating, why can't I take a snip of the "Choose another app" box so I can show you that I'm setting it right?

microsoft print to pdf files will not open after saving

We suggest that you save the PDF files on your device and check if the issue persists. You may also want to associate the PDF files to Microsoft Edge as the default program to make sure that you have a default application that will open all of your PDF files.
Here are the steps:

• Search for Default Programs.
• Go to Associate a file type or protocol with a program.
• Select the .pdf file type and then click the Change program button on the upper right of the
  Set Associations window.
• Choose Microsoft Edge and then click OK.

Let us know how it goes.

 

How to change the default program that opens PDF files (Windows 7)

The easiest way is to install a program that opens PDF files and during the installation select the option to use that program.

If you already have installed the program that you want to use to open PDF files, just right-click on any PDF file and select "Open with > Choose default program..." Then select your program from the list, make sure the box at the lower left is checked
to "Always use the selected program to open this kind of file" and then click OK.
