Windows 10 September 2022 Patch Tuesday (KB5017308) out — here's what's new and what's broke

Windows 10 Patch Tuesday

It's the second Tuesday of the month, which means it's Patch Tuesday time again. As such, today Microsoft is rolling out the monthly security update (also called "B release") for September 2022 on Windows Server 20H2, and Windows 10 for the latest versions, 21H1, 21H2. The new updates are being distributed under KB5017308, bumping up the builds to 19042.2006, 19043.2006, and 19044.2006. You can find standalone links to download the new update on Microsoft Update Catalog at this link here.

The major highlight of the release is security updates for Windows 10 and as is generally the case, the Redmond company has also listed the known issues in the update, which is always handy. Here are the symptoms and their respective workarounds:

Symptoms	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: 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 Extract the SSU from the previously extracted cab via this command line: expand Windows10.0-KB5000842-x64.cab /f:* 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 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.	We are working on a resolution and will provide an update in an upcoming release.
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.	To mitigate this issue, please see one of the following: Windows 10, version 21H2: Possible issues caused by new Daylight Savings Time in Chile Windows 10, version 21H1: Possible issues caused by new Daylight Savings Time in Chile Windows 10, version 20H2: Possible issues caused by new Daylight Savings Time in Chile We are working on a resolution and will provide an update in an upcoming release. Note We plan to release an update to support this change; however, there might be insufficient time to properly build, test, and release such an update before the change goes into effect. Please use the workaround above.

Symptoms

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:

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