Microsoft released the November 2026 security update for Windows 11 on Tuesday, November 10, 2026 (Patch Tuesday). On Windows 11 versions 26H2, 25H2 and 24H2 (Enterprise and Education), it is KB5132061 (OS Builds 26300.9974, 26200.9974 and 26100.9974); on version 23H2 it is KB5131087 (OS Build 22631.7711). Besides the usual security fixes, it fixes the USB Audio 1.0 “code 10” issue, an RDP certificate problem and an Active Directory printer error, enables NTLM signing by default on the client side and tightens PowerShell script signature checks. Here is what Microsoft documents, and who it concerns.

KB5132061: Windows 11 version 26H2 (build 26300.9974) and 25H2 (26200.9974), all editions, and Windows 11 Enterprise and Education version 24H2 (26100.9974).

KB5131087: Windows 11 version 23H2 (build 22631.7711).

KB5132061 includes the servicing stack update KB5132688 (build 26100.9971) and the improvements from the October updates KB5127648, KB5134133 (out-of-band) and KB5127936 (preview).

To check, open Settings > Windows Update > Check for updates, then type winver after the restart to see your build.

USB audio: USB Audio 1.0 devices could fail to start with error code 10 in Device Manager after a recent security update. Microsoft lists this known issue as fixed. On 24H2 Enterprise/Education, the update also fixes HDMI and DisplayPort audio playback failing on certain AMD graphics cards. Background on the issue: our article on the USB Audio code 10 known issue.

Remote Desktop: RDP connections could fail on the client because of a certificate mismatch after the October 2026 non-security preview update.

Printing: adding a printer published in Active Directory via Settings > Bluetooth & devices > Printers & scanners > Add device could fail with error 87 (“The parameter is incorrect”). Microsoft says this came from the October 2026 update and does not generally affect existing printers.

Time zone: new daylight saving time rules for Cuba (stays on UTC-04:00 through the 2026-2027 period).

NTLM: clients now offer NTLM message signing by default for non-anonymous connections, to reduce exposure to NTLM relay attacks, with auditing to spot connections that do not use signing.

PowerShell: script signing and signature verification use stricter encoding validation. Scripts with invalid UTF-8 may now fail signature validation even if they were accepted before. Microsoft’s fix: save the script as valid UTF-8 with a BOM and sign it again.

Secure Boot: more devices become eligible to automatically receive the new Secure Boot certificates; the rollout continues in the coming months.

The details of the vulnerabilities fixed are in Microsoft’s Security Update Guide; the KB page does not list them.

When we read the KB5132061 page (November 10, 2026, around 7:20 p.m. Paris time), Microsoft said it was “not currently aware of any issues” with this update. This can change: check the page again before deploying at scale.

No December 2026 non-security preview update: Microsoft says there will be none in the second half of December because of the holidays; normal servicing resumes in January 2027.

KB5132061 also updates AI components (Image Search, Content Extraction, Semantic Analysis, Settings Model) to version 1.2610.1063.0.

According to the Windows message center, Windows 11 version 23H2 Enterprise and Education editions reach end of updates on November 10, 2026: the November 2026 security update (KB5131087) is the last one available for these editions. Microsoft recommends moving eligible devices to a supported version of Windows 11 via Settings > Windows Update.
