Windows 10 has Edge as its default web browser instead of Microsoft’s traditional web browser, Internet Explorer, in all the devices. Also, Microsoft Edge is now the default pdf reader to open and view pdf files in Windows 10 supported workstations.

Unable to Open PDF Files in MS Edge?

The earlier versions of Windows (Windows 7 or Windows 8/8.1) have a universal PDF support that allows opening PDF files using Acrobat Reader, Adobe Acrobat, Foxit Reader, or similar programs. But after making an upgrade to Windows 10, PDF files are automatically opened in PDF Explorer even if the Acrobat Reader is installed on the machine.

Microsoft Edge provides only minimal access controls (like zoom in, zoom out, print, etc.) and lacks some convenient features, like, sending the PDF as an attachment with Outlook. Also, the file can become inaccessible, and MS Edge may indicate some error messages. Simply, Edge users often face issues while opening PDF files in their browser.
