Known Issues
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. The IE mode tabs in Microsoft Edge might stop responding when a site displays a modal dialog box – a form or dialog box that requires the user to respond before continuing with other portions of the webpage or app. If you are impacted by the issue after installing the update, Microsoft suggests using the Known Issue Rollback (KIR) Group Policy, which can be downloaded from the link below: Download Known Issue Rollback Group Policy for Windows 10 Note: The policy will need to be installed and configured according to your Windows version, which you can confirm by typing in winver in the Run Command box. There are reports that there are issues with some printing devices, and may result in duplicate copies of the same printer installed on your computer.
