Overall update known issues

  • Devices with Windows installations created from custom offline media or custom ISO image may lose the Microsoft Edge legacy without being replaced by the new Microsoft Edge after the upgrade. This problem only occurs when creating ISO images or custom offline media without first installing the Independent Servicing Stack (SSU) update released on or after March 29, 2021.
    • To avoid this problem, be sure to embed the SSU, which was first released on March 29, 2021, in a custom offline media or ISO image before embedding it in the LCU. To do this with the SSU and LCU combo packages currently in use for Windows 10 version 20H2 and Windows 10 version 2004, you need to extract SSU from the combo package.
