Back in July i did a blog post on how to deploy Edge Dev with Intune – that guide is also working for Edge Beta.

This is a short blog post on how to set Edge Beta as the default browser in Windows 10 with Intune. When starting testing the Edge beta app in your organisation it is also a great idea to set it as the default browser to give the best user experience.
You can also setup other default apps then the browser – by chancing the default apps in Windows Settings app and then export is as a .xml file.

From the Set Microsoft Edge as the default browser documentation you can copy the DefaultAssociations.xml that you need, you can also create your own : By running dism from an elevated prompt, run “dism /online /export-defaultappassociations:appassoc.xml”

<?xml version=”1.0″ encoding=”UTF-8″?>
<Association ApplicationName=”Microsoft Edge Beta” ProgId=”MSEdgeBHTML” Identifier=”.html”/>
<Association ApplicationName=”Microsoft Edge Beta” ProgId=”MSEdgeBHTML” Identifier=”http”/>
<Association ApplicationName=”Microsoft Edge Beta” ProgId=”MSEdgeBHTML” Identifier=”https”/>

Now you just need to find a Base64 encoder in this case I used a online from


Got the result that you need in your Intune profile: PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4NCjxEZWZhdWx0QXNzb2NpYXRpb25zPg0KICA8QXNzb2NpYXRpb24gQXBwbGljYXRpb25OYW1lPSJNaWNyb3NvZnQgRWRnZSBCZXRhIiBQcm9nSWQ9Ik1TRWRnZUJIVE1MIiBJZGVudGlmaWVyPSIuaHRtbCIvPg0KICA8QXNzb2NpYXRpb24gQXBwbGljYXRpb25OYW1lPSJNaWNyb3NvZnQgRWRnZSBCZXRhIiBQcm9nSWQ9Ik1TRWRnZUJIVE1MIiBJZGVudGlmaWVyPSJodHRwIi8+DQogIDxBc3NvY2lhdGlvbiBBcHBsaWNhdGlvbk5hbWU9Ik1pY3Jvc29mdCBFZGdlIEJldGEiIFByb2dJZD0iTVNFZGdlQkhUTUwiIElkZW50aWZpZXI9Imh0dHBzIi8+ICANCjwvRGVmYXVsdEFzc29jaWF0aW9ucz4=

Now you are ready to create your own profile in Intune:

Start Microsoft 365 Device Management portal

  1. Click Device Configuration
  2. Click Profiles
  3. Click Add
Intune default browser - 01
  1. Name: Edge Beta Default Browser
  2. Platform : Windows 10 and later
  3. Profile type: Custom
  4. Click Settings
  5. Click Add

Intune default browser - 05

  1. Name: Set Default apps
  2. Description : Edge Beta
  3. OMA-URI : ./Vendor/MSFT/Policy/Config/ApplicationDefaults/DefaultAssociationsConfiguration
  4. Data type: String
  5. Value : the Base64 value you found earlier

Intune default browser - 03

Then you can deploy the profile to your end user.

After the profile as been applied onto the devices and the end user has done a login Edge Beta is set a default browser app on your Windows 10 device
