Windows 10: Default app for htm keeps reverting to MS Edge

This has been getting annoying. It's been happening several times a day, not just after an update. Anybody else seeing this?

Unfortunately you can't uninstall Edge ... *Rolleyes

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?

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 Configure a Windows Repair Source.

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:

Hello DJG, *Smile

You might see if the tutorial below may be able to help if it's for the same notification in the tutorial.

An app default was reset - Fix in Windows 10

 

One reason that can trigger a string of 'an app default was reset' notifications is using an older program that employs methods of checking and setting defaults that have been deprecated. If the notification occurs after using one particular program then look to see if an updated version is available. For this particular OP the culprit was an old version of Infranview (for which there is an update that works properly).

Setting up Windows 10 Pro

 

Thanks Brink. Mind you I don't get a notification, I just get Edge opening them again without notice.

I just applied the reg edit only for Edge from your file. Let's see what happens *Smile.

Thanks!

 

Well, that made it so it ALWAYS uses Edge and Open with another cannot switch it even temporarily - there's no "Always use" option.

Sigh ...

 

You might see if you may be able to use one of the other options below to set the default app for the file type.

Default Apps - Choose in Windows 10

 

Thanks, Brink. Maybe reverting will resume normal behavior - let's see how long it lasts *Smile

 

No such luck - again Edge claims it must open html files. This is so annoying! Anybody know of a way to disable Edge? Maybe renaming it to EdgeSucks.exe or something?

 

OK, since I ran Win update KB3216755 things have been back to normal.
