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:

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 namedSSU-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 this update, XPS Viewer might be unable to open XML Paper Specification (XPS) documents in some non-English languages, including some Japanese and Chinese character encodings. This issue affects both XML Paper Specification (XPS) and Open XML Paper Specification (OXPS) files. When encountering this issue, you may receive an error, “This page cannot be displayed” within XPS Viewer or it might stop responding and have high CPU usage with continually increasing memory usage. When the error is encountered, if XPS Viewer is not closed it might reach up to 2.5GB of memory usage before closing unexpectedly.This issue does not affect most home users. The XPS Viewer is no longer installed by default as of Windows 10, version 1803 and must be manually installed.| This issue is addressed in KB5017380.
   Starting at 12:00 A.M. Saturday, September 10, 2022, the official time in Chile will advance 60 minutes in accordance with the August 9, 2022 official announcement by the Chilean government about a daylight saving time (DST) time zone change. This moves the DST change which was previously September 4 to September 10.Symptoms if the workaround is not used on devices between September 4, 2022 and September 11, 2022:

• ​Time shown in Windows and apps will not be correct.
• ​Apps and cloud services which use date and time for integral functions, such as Microsoft Teams and Microsoft Outlook, notifications and scheduling of meetings might be 60 minutes off.
• ​Automation that uses date and time, such as Scheduled tasks, might not run at the expected time.
• ​Timestamp on transactions, files, and logs will be 60 minutes off.
• ​Operations that rely on time-dependent protocols such as Kerberos might cause authentication failures when attempting to logon or access resources.
• ​Windows devices and apps outside of Chile might also be affected if they are connecting to servers or devices in Chile or if they are scheduling or attending meetings taking place in Chile from another location or time zone. Windows devices outside of Chile should not use the workaround, as it would change their local time on the device.

  After installing this update, file copies using Group Policy Preferences might fail or might create empty shortcuts or files using 0 (zero) bytes. Known affected Group Policy Objects are related to files and shortcuts in User Configuration >**Preferences **>Windows Settings in Group Policy Editor.| This issue was addressed in KB5018410. Installation of this update prevents and resolves this issue, but if any workaround was used to mitigate this issue, it will need to be changed back to the original configuration.

How to get this update

Before installing this updateMicrosoft 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:Based on your installation scenario, choose one of the following:

1. For offline OS image servicing:If your image does not have the March 22, 2022 (KB5011543) or later LCU, you mustinstall the special standalone May 10, 2022 SSU (KB5014032) before installing this update.
2. 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 (KB5003173) or later LCU, you mustinstall the special standalone August 10, 2021 SSU (KB5005260) before installing this update.
   Install this update****Release Channel|Available|Next Step

   Windows Update and Microsoft Update| Yes| None. This update will be downloaded and installed automatically from Windows Update.
   Windows Update for Business| No| No longer available.
   Microsoft Update Catalog| No| No longer available.
   Windows Server Update Services (WSUS)| No| No longer available.

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. You cannot remove the SSU from the system after installation.
