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.NoteDevices 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 latest cumulative update (LCU) without any extra steps. | To avoid this issue, be sure to first slipstream the SSU released March 29, 2021 or later into the custom offline media or ISO image before slipstreaming the LCU. To do this with the combined SSU and LCU packages now used 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: |
0x000006e4 (RPC_S_CANNOT_SUPPORT)
0x0000007c (ERROR_INVALID_LEVEL)
0x00000709 (ERROR_INVALID_PRINTER_NAME)
Note The printer connection issues described in this issue are specific to print servers and are not commonly observed in devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.| This issue is resolved in KB5007253.
After installing this update, Microsoft Installer (MSI) might have issues repairing or updating apps. Apps that are known to be affected include some apps from Kaspersky. Affected apps might fail to open after an update or repair has been attempted.| This issue is resolved in KB5007253.

App packages with framework dependencies
Apps that are provisioned for the device, not per user account.
The affected apps will fail to open without error messages or other observable symptoms. They must be re-installed to restore functionality.| This issue is addressed in KB5015878 for all releases starting June 21, 2021 and later.
