Microsoft Edge missing after using custom media/ISOs including March 29, 2021 updates Microsoft Edge missing when installing Windows from custom media/ISOs using updates released March 25, 2021 or later. OS Build 19042.906 KB50-03-29: Resolved: 2021-03-29 17:01 PT. Dell only sells Windows installation media when ordered with a system. If you want to reinstall a Windows Server OS on your PowerEdge server, but you lost your original Windows Installation-DVD, you can download the matching ISO-file directly from Microsoft (after registration). Then we could delete Google Chrome in our environment, if Microsoft Edge will be supported on Server OS. In our Citrix environment we are still using Server 2008 R2, but we are getting ready to get on Server 2016 instead (hopefully Server 2019 if Citrix will support it soon). So I would like to see Microsoft Edge on those Server OS.
Windows 10, version 20H2 is available for users with devices running Windows 10, who manually seek to “Check for updates” via Windows Update. We have started a new phase in our rollout. Using the machine learning-based (ML-based) training we have done so far, we are increasing the number of devices that are approaching end of service to update automatically to Windows 10, version 20H2. We will continue to train our machine learning through all phases to intelligently rollout new versions of Windows 10 and deliver a smooth update experience. The recommended servicing status is Semi-Annual Channel. Note We are slowly throttling up availability over the coming weeks to ensure a reliable download experience. As a result, the update may not be offered to you right away. For more details, see How to get the Windows 10 October 2020 Update. |

Devices with Windows installations created from custom offline media or custom ISO image might have Microsoft Edge Legacy removed by this update, but not automatically replaced by the new Microsoft Edge. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone Servicing Stack Update (SSU) released March 29, 2021 or later. Note Devices that connect directly to Windows Update to receive updates are not affected. This includes devices using Windows Update for Business. Any device connecting to Windows Update should always receive the latest versions of the Servicing Stack Update (SSU) and latest cumulative update (LCU) without any extra steps. Workaround: If you have already encountered this issue by installing the OS using affected custom media, you can mitigate it by directly installing the new Microsoft Edge from here.
