Known issues in KB5028166

An issue with the standalone (clean) installation of Windows 10 with this update is causing Microsoft Edge Legacy to be removed. However, it is not being replaced by the new Chromium-based Edge.

This occurs only when Windows has a custom offline media or an ISO image installed that does not include the 29th March 2021 SSU update. Microsoft suggests that you either install the March SSU update through slipstreaming or simply update an existing OS through Windows Update, so you will not be facing this issue.

Alternatively, you can simply download and install the new Microsoft Edge if you have already encountered this problem.

This issue has been around for a while and Microsoft still hasn’t fixed it.
