Set Microsoft Edge as default browser

If you set this policy to True, Microsoft Edge always checks whether it's the default browser on startup and, if possible, automatically registers itself.

If you set this policy to False, Microsoft Edge is stopped from ever checking if it's the default and turns user controls off for this option.

If you don't set this policy, Microsoft Edge lets users control whether it's the default and, if not, whether user notifications should appear.

Note for Windows administrators: This policy only works for PCs running Windows 7. For later versions of Windows, you have to deploy a "default application associations" file that makes Microsoft Edge the handler for the https and http protocols (and, optionally, the ftp protocol and file formats such as .html, .htm, .pdf, .svg, .webp). See https://go.microsoft.com/fwlink/?linkid=2094932 for more information.

Supported on: Microsoft Edge version 77, Windows 7
