October 12, 2021—KB5006670 (OS Builds 19041.1288, 19042.1288, and 19043.1288)

Symptom

Workaround

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 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:

1. Extract the cab from the msu via this command line (using the package for KB5000842 as an example): expand Windows10.0-KB5000842-x64.msu /f:Windows10.0-KB5000842-x64.cab <destination path>

2. Extract the SSU from the previously extracted cab via this command line: expand Windows10.0-KB5000842-x64.cab /f:* <destination path>

3. You will then have the SSU cab, in this example named SSU-19041.903-x64.cab. Slipstream this file into your offline image first, then the LCU.

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. If you need to broadly deploy the new Microsoft Edge for business, see Download and deploy Microsoft Edge for business.

After installing the June 21, 2021 (KB5003690) update, some devices cannot install new updates, such as the July 6, 2021 (KB5004945) or later updates. You will receive the error message, "PSFX_E_MATCHING_BINARY_MISSING".

For more information and a workaround, see KB5005322.

After installing KB5005565, installation of printers using Internet Printing Protocol (IPP) might not complete successfully. Devices which had connected to and installed the printer prior to the installation of KB5005565 are unaffected and print operations to that printer will succeed as usual.

Note IPP is not commonly used by devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.

This issue is resolved in KB5006738.

After installing this update, when connecting to devices in an untrusted domain using Remote Desktop, connections might fail to authenticate when using smart card authentication. You might receive the prompt, "Your credentials did not work. The credentials that were used to connect to [device name] did not work. Please enter new credentials." and "The login attempt failed" in red.

This issue is addressed in KB5007253.

After installing this update, Windows print clients might encounter the following errors when connecting to a remote printer shared on a Windows print server:

• 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.

When attempting to reset a Windows device with apps that have folders with reparse data, such as OneDrive or OneDrive for Business, files which have been downloaded or synced locally from OneDrive might not be deleted when selecting the “Remove everything” option. This issue might be encountered when attempting a manual reset initiated within Windows or a remote reset. Remote resets might be initiated from Mobile Device Management (MDM) or other management applications, such as Microsoft Intune or third-party tools. OneDrive files that are “cloud only” or have not been downloaded or opened on the device are not affected and will not persist, as the files are not downloaded or synced locally.

Note Some device manufacturers and some documentation might call the feature to reset your device, "Push Button Reset", "PBR", "Reset This PC", "Reset PC", or "Fresh Start".

This issue was addressed in KB5011487. Some devices might take up to seven (7) days after the installation of KB5011487 to fully address the issue and prevent files from persisting after a reset. For immediate effect, you can manually trigger Windows Update Troubleshooter using the instructions in Windows Update Troubleshooter. If you are part of an organization that manages devices or prepared OS images for deployment, you can also address this issue by applying a compatibility update for installing and recovering Windows. Doing that makes improvements to the "safe operating system" (SafeOS) that is used to update the Windows recovery environment (WinRE). You can deploy these updates using the instructions in Add an update package to Windows RE using KB5012419 for Windows 10, version 21H2, Windows 10, version 21H1, and Windows 10, version 20H2.

Important If devices have already been reset and OneDrive files have persisted, you must use a workaround above or perform another reset after applying one of the workarounds above.
