Windows 10: Edge hijacking the .HTM and/or .HTML extention

I have gone through re-associating .HTML files to Firefox over and over and over again. But days later, once again Edge is Hijacking the .HTML file extension.It is a recurring problem.With .PDF files there is a MS Edge Policy [ AlwaysOpenPdfExternally=1 ] but there is no .HTML policy.I have a specific HTML application that denies Edge Use. So I want .HTML to permanently be associated to Firefox.I am tired of going through the PITA process, over and over again, of choosing Settings --> Apps to re-associate the extension back to Firefox.Either Microsoft has to fix the issue but their hubri

Can't stop Microsoft Edge from hijacking .pdf and .htm files

Hi again,

Before reinstalling Windows I decided to try registry changes. It seems to do the trick!

Here is what I did:

1) Start Regedit

Search for regedit.exe

Open regedit as administrator by right click on it and choose "run as administrator"

2) Find keys identifying the hijacking

a) Expand HKEY_CURRENT_USER\SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\Repository\Packages

b) Locate Microsoft Edge

In my case

Microsoft.MicrosoftEdge_38.14393.0.0_neutral__8wekyb3d8bbwe

Expand Microsoft.MicrosoftEdge_38.14393.0.0_neutral__8wekyb3d8bbwe => MicrosoftEdge => Capabilities

Look at all the file extension keys and their values

Make a note of the values for file extensions that Edge hijacks.

In my case I have these hijacked file extensions:

.pdf => AppXd4nrz8ff68srnhf9t5a8sbjyar1cr723

.htm => AppX4hxtad77fbk3jkkeerkrm0ze94wjf3s9

.html > AppX4hxtad77fbk3jkkeerkrm0ze94wjf3s9

In my example there where 2 different hijacking keys that Edge uses to hijack my .pdf and .htm files:

AppXd4nrz8ff68srnhf9t5a8sbjyar1cr723

AppX4hxtad77fbk3jkkeerkrm0ze94wjf3s9

Repeat 2b if you have other hijacking apps from Microsoft (other than Edge) i.e. Groove music hijacking .mp3 etc.

3) Locate those hijacking keys and add strings to make Edge keep off

a) For each hijacking key

Expand HKEY_CURRENT_USER\SOFTWARE\Classes\<hijacking key>

Example: Expand HKEY_CURRENT_USER\SOFTWARE\Classes\AppXd4nrz8ff68srnhf9t5a8sbjyar1cr723

Select the Hijacking key in the left pane.

b) In the right pane, right click and select New => String Value

Set Value Name to NoOpenWith

(Leave Data empty)

Repeat b, but the second String Value is named NoStaticDefaultVerb

Repeat 3 for each hijacking key

Exit regedit

Go to Windows Settings, search for "Choose default app for each file type". Find your file extensions and select your favorite apps.

Done!

Final note:

Hijacking might resume when windows is updated, so you might need to go through all these steps again if this happens.

Somebody should make an app fixing these settings automatically! I see a great market potential!

Best regards,
