Microsoft has released Windows 11 KB5132061 update for versions 26H2, 25H2, and 24H2. The November 2026 update includes important security patches, quality improvements, and several features previously introduced in the KB5127936 preview release.
Unlike preview updates, KB5132061 is a mandatory Patch Tuesday security release that includes significant vulnerability fixes, authentication security improvements, and reliability updates. Businesses and IT administrators will particularly benefit from the strengthened NTLM protections, Secure Boot certificate deployment improvements, and fixes for Remote Desktop and Active Directory printer deployments.
Most users can install this update through Windows Update on their home PCs. For organizations, the security content alone makes deployment a priority. Administrators looking to deploy the November 2026 update can use enterprise update management solutions such as WSUS, Configuration Manager, and Microsoft Intune.
Fixes and improvements in the KB5132061 update
The Windows 11 November 2026 update includes security and quality improvements:
- Security: Resolves vulnerabilities; enhances NTLM security to mitigate relay attacks; auditing for unsigned connections.
- Secure Boot: Expands device targeting for automatic new certificate deployment.
- Audio: Fixed USB Audio 1.0 devices failing with error code 10 after updates.

Deploy Windows 11 November 2026 Update using Intune
The Windows 11 KB5132061 update can be deployed by configuring an expedite policy in Intune and assigning it to the appropriate groups containing Windows 11 26H2, 25H2, and 24H2 devices. For more information, see how to expedite Windows quality updates in Intune.
- Sign in to the Intune admin center. Go to Devices > Windows > Windows Updates > Quality Updates.
- Create a new Expedite policy and enter a descriptive name for the profile.
- Select the Windows quality update “11/10/2026 – 2026.11 B Security Update for Windows 10 and later” from the drop-down list.

On the Assignments tab, select Add groups and then select device or user groups to assign the policy. Click Next. On the Review+Create page, take a look at the expedite policy settings. If it’s all good, click Create. After the policy is created, it is deployed to assigned groups.
Installing KB5132061 Update using WSUS/SCCM
Organizations that rely on WSUS or Configuration Manager to distribute software updates to on-premise devices can deploy the KB5132061 update efficiently. If you don’t see the update either in WSUS or SCCM, you must manually import the update into WSUS.
If you’re using WSUS standalone in your setup, right-click the update and approve it. I suggest rolling out the update to a group of pilot devices initially, and once confirmed that the update causes no issues, proceed to deploy it across all Windows 11 devices. The deployment occurs based on the schedule you’ve configured.
To patch the same update using Configuration Manager, ensure you open the console and synchronize the software updates. This will display all the latest updates from WSUS, including those you manually imported into the console.
Once the sync is complete, go to Software Library > Software Updates > All Software Updates. In the search bar, type “KB5132061” and click search. You should now see the update 2026-11 Cumulative Update for Windows 11, version 26H2 for x64-based Systems (KB5132061) (26300.9974) listed in the console. From here, you can refer to the SCCM patching guide to deploy it to your Windows devices.
KB5132061 Known Issues
No known issues have been reported with this update. However, if you intend to deploy it to Windows 11 devices using SCCM or Intune in your organization, it’s advisable to first install it on a pilot group of devices. After thorough testing, you can proceed to roll it out to a broader group of devices.
Uninstalling the Update
If you haven’t installed the Windows 11 November 2026 update yet, you may pause updates in Settings. If you’ve already installed the update and you are encountering some known issues, go to Settings > Windows Update > Update history > Uninstall updates. Alternatively, you may also use PowerShell to list the updates and uninstall them.
Lastly, here’s a comprehensive guide by me detailing the updates released for each version of Windows 11, including their respective KB numbers and build numbers.
