Default associations for .HTM .HTML and .PDF keep reverting to Edge

Default associations for .HTM .HTML and .PDF keep reverting to Edge. No matter how I try to change either through File Explorer or Control Panel > Default Programs, it will always revert back to Edge. It is intolerable. Is there a known issue here? Or how do I go about uninstalling Edge because that doesn't seem possible either? 

Hi Stephen,

Thank you for posting your query in Microsoft Community.

I apologize for the inconvenience caused. We are glad to help you.

Before assisting further, I would like to ask you few questions:

1.      Did you check if the issue persists in another user profile?

2.      Since when are you facing this issue/

3.      Do you get any error message?

You may be facing the above issue due to missing system files or presence of corrupted files & folders on your PC. Missing certain system files or presence of corrupted files & folders may cause some of the performance issues on the system apps or on the PC.

Method 1: Run SFC scan and DISM scan on your PC by following the steps below and check if the issue is resolved.

SFC scan is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected. For example, some Windows functions may not work, or Windows may crash.

Windows corruption errors may prevent Windows updates and service packs from installing. For example, an update might not install if a system file is damaged. The DISM scan or System Update Readiness tool may help you to fix some Windows corruption errors. 

Step 1: Open an Administrator command prompt window by following this: 

1.      Press Windows logo + X keys on the keyboard and select Command Prompt (Admin) option.

2.      Click on Yes and continue. Provide administrator password if prompted.

3.      Check if it says Administrator: Command Prompt at the top of the command prompt window.

Step 2: Type the following commands in the CMD Prompt: 

            dism /online /cleanup-image /restorehealth

            sfc /scannow

 Close the command window and check if the issue is resolved.

Hope this information helps. Do get back to us with the updated status. We will be happy to assist you.

Regards,

Jenith

Thanks Jenith,

DISM returns the following error:

Error: 0x800f081f

The source files could not be found.
Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see http://go.microsoft.com/fwlink/?LinkId=243077.

The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

The http link refers to "Configure a Windows Repair Source" which states "Windows Update will be used by default..." which obviously it isn't.

And SFC reports the following:

Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not
supported in offline servicing scenarios.

And this is part of the log:

This issue seems to be very common with some of the latest Windows 10 updates. Common, really Microsoft?
