Setting Edge browser as your default browser is easy and straightforward but how about setting it up on multiple computers or multiple users on a terminal server?

The quick answer would be via Group Policy.

First, we will need to prepare an Association Configuration file. Copy the following content as an XML file, such as assoc.xml.

<?xml version="1.0" encoding="UTF-8"?>
<DefaultAssociations>
  <Association ApplicationName="Microsoft Edge" ProgId="MSEdgeHTM" Identifier=".html"/>
  <Association ApplicationName="Microsoft Edge" ProgId="MSEdgeHTM" Identifier=".htm"/>
  <Association ApplicationName="Microsoft Edge" ProgId="MSEdgeHTM" Identifier="http"/>
  <Association ApplicationName="Microsoft Edge" ProgId="MSEdgeHTM" Identifier="https"/>  
</DefaultAssociations>

Now, open the Group Policy editor and go to the following location:

Computer Configuration\Administrative Templates\Windows Components\File Explorer

And enable the policy “Set a default associations configuration file and specify the location of the XML file you just created above.

And that’s it. Apply it to an OU and any users who use anything inside that OU will have Edge as their default browser.
