Microsoft’s November 10, 2026 cumulative updates fix remaining USB audio failures and restore some on-premises Exchange sign-ins.

Microsoft’s November 10, 2026 cumulative updates address known issues left by earlier security updates. USB Audio Class 1.0 devices on Windows 10, Windows 11, and Windows Server 2012 and later could fail to start, show Code 10 errors, or lose multichannel modes; KB5132061 and later cover what September 14 out-of-band updates did not. Windows 10 KB5131096, for Enterprise LTSC and Extended Security Update devices, reaches build 19045.7846, or 19044.7846 on Enterprise LTSC 2021, and includes November Patch Tuesday fixes. BleepingComputer says those fixes address 1,235 vulnerabilities, including one actively exploited Outlook zero-day, plus printer, Remote Desktop, and PowerShell signature issues. Microsoft says October Windows Server updates—not October Exchange updates—broke Outlook sign-in and mail delivery on some on-premises Exchange servers running Server 2019 and later; KB5131080 and KB5131090 fix the Endpoint Mapper limit.
