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.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: |
Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\current\device\Bluetooth\
Add the following registry entry: {0000110a-0000-1000-8000-00805f9b34fb} and {0000110b-0000-1000-8000-00805f9b34fb} to the ServicesAllowedList value
Note If you have already installed the update and the blue screen error message appears during the device’s restart, open Windows in SafeOS mode to add the registry entry.This issue is addressed using a Known Issue Rollback (KIR). This KIR will not propagate to devices automatically. Devices that have installed an affected update and encountered this issue can address it by installing and configuring a special Group Policy. After you download and install the special Group Policy, configure it using the following steps:
Open Group Policy Editor and go toLocal Computer Policyor theDomain policy on your domain controller.
Then go to Administrative Templates >KB5009596 Issue 001 Rollback>Windows 10, versions 2004, 20H2, and 21H1, and set it to “Disabled”.
Restart the affected device.NoteIf you are setting this on a domain controller, you must wait for the Group Policy to propagate and then restart the affected devices. You don’t need to restart the domain controller after installing this KIR Group Policy.
Allow Group Policy to refresh on the affected devices before installing the affected Windows update.
For more information about deployment, see How to use Group Policy to deploy a Known Issue Rollback.
After installing the Windows updates released January 11, 2022 or later Windows versions on an affected version of Windows, recovery discs (CD or DVD) created by using the Backup and Restore (Windows 7) app in Control Panel might be unable to start.Recovery discs that were created by using the Backup and Restore (Windows 7) app on devices which have installed Windows updates released before January 11, 2022 are not affected by this issue and should start as expected.NoteNo third-party backup or recovery apps are currently known to be affected by this issue| This issue is addressed in KB5014023.
We are receiving reports that the Snip & Sketch app might fail to capture a screenshot and might fail to open using the keyboard shortcut (Windows key+shift+S). This issue occurs after installing KB5010342 (February 8, 2022) and later updates.| This issue is addressed in KB5014666.

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).Install this update****Release Channel | Available | Next Step |

If you want to remove the LCUTo 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.
