Microsoft Edge keeps making itself the default PDF viewer Fix

We all know that Microsoft Edge comes with an in-built PDF reader and Windows recommends using Microsoft Edge to read PDF files Online and Offline. Also, Microsoft Edge will be used as the default PDF reader in Windows 10 and Windows 11. However, everyone has their own preference for the PDF reader to be used. Suppose, we change the PDF reader to say Acrobat Reader or any other PDF reader of our choice, we notice that after few days the file association for the PDF files will be changed to Microsoft Edge again. It can be very annoying as we have to change the file association again and again after few days.
