Stopping PDF files from opening on Microsoft Edge is pretty simple; this article will show you how you can do it.

Update Your PDF Viewer

Sometimes, if your preferred PDF viewer is outdated or obsolete, Windows will change the default PDF Viewer to Microsoft Edge after each reboot. This happens if you’re using old PDF viewers like Adobe Acrobat 11 or 12. Softwares from 10 years ago won’t be efficient either, so it’s best to make sure that you’re using the latest version of the app.
