This policy lets a user run Microsoft Edge (Edge HTML) and Microsoft Edge (Chromium-based) side-by-side.
If this policy is set to "Not configured", Microsoft Edge (Chromium-based) will replace Microsoft Edge (Edge HTML) after the Microsoft Edge (Chromium-based) stable channel and the November 2019 security updates are installed. This is the same behavior as the "Disabled" setting.
The "Disabled" setting blocks a side-by-side experience and Microsoft Edge (Chromium-based) will replace Microsoft Edge (Edge HTML) after the Microsoft Edge (Chromium-based) stable channel and the November 2019 security updates are installed. This is the same behavior as the "Not Configured" setting.
When this policy is "Enabled", Microsoft Edge (Chromium-based) and Microsoft Edge (Edge HTML) can run side-by-side after Microsoft Edge (Chromium-based) is installed.
For this group policy to take affect, it must be configured before the automatic install of Microsoft Edge (Chromium-based) by Windows Update. Note: A user can block the automatic update of Microsoft Edge (Chromium-based) by using the Microsoft Edge (Chromium-based) Blocker Toolkit.
Starting with Windows 10 version 20H2 Microsoft Edge Legacy and the side-by-side browser experience are not supported.
