Windows 10 servicing stack update - 19041.1310, 19042.1310, and 19043.1310

Known issues in this update
|
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:
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. |

For more information and a workaround, see KB5005322. |

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.

Please enter new credentials." and "The login attempt failed" in red. |

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. |
|
Universal Windows Platform (UWP) apps might not open on devices that have undergone a Windows device reset. This includes operations that were initiated using Mobile Device Management (MDM), such as Reset this PC, Push-button reset, and Autopilot Reset. UWP apps you downloaded from the Microsoft Store are not affected. Only a limited set of apps are affected, including:
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. |
How to get this update
Before installing this update
Microsoft now combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.
Prerequisite:
For Windows Server Update Services (WSUS) deployment or when installing the standalone package from Microsoft Update Catalog:
If your devices do not have the May 11, 2021 update (KB5003173) or later LCU, you must install the special standalone August 10, 2021 SSU (KB5005260).

If you want to remove the LCU
To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.
Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.
