|Devices with Windows installations created from custom offline media or a custom ISO image may have Microsoft Edge Legacy removed by this update, but not automatically replaced by the new Microsoft Edge. This issue only occurs when custom offline media or ISO images are created by embedding this update in the image without first installing the Standalone Servicing Stack (SSU) update released on March 29. 2021 or later.
To 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 SSU and the latest cumulative update (LCU) without any additional steps.
|To avoid this issue, make sure to first integrate the SSU released on March 29, 2021 or later into the custom offline media or ISO image before integrating the LCU. To do this, with the combined SSU and LCU packages now in use for Windows 10, version 20H2 and Windows 10, version 2004, you will need to extract the SSU from the combined package. Use the following steps to extract the SSU using:
If you have already encountered this problem by installing the operating system using the affected custom media, you can mitigate it by directly installing the new Microsoft Edge. If you need to scale up the new Microsoft Edge for business, see Download and deploy Microsoft Edge for business
