Microsoft releases emergency Windows 11 update to fix record-breaking September Patch Tuesday

Microsoft has released an emergency out-of-band Windows update to fix Remote Desktop, USB audio and Hyper-V problems caused by its record-breaking September Patch Tuesday release.

The emergency update, released yesterday, addresses Remote Desktop, USB audio and Hyper-V issues, according to The Verge. The September Patch Tuesday affected folder shares on Hyper-V-based Linux virtual machines, Remote Desktop Services sessions, and some USB audio devices.

The out-of-band update applies to Windows 11 versions 26h1, 25H2 and 24H2. Microsoft also released updates for Windows Server 2025 and 2022, the LTSC versions of Windows 10, and Windows Server 2012 and Windows Server 2012 R2.

Out-of-band updates were once unusual for Microsoft, but they have become far more common this year. In January, the company was forced to issue four out-of-band updates after a buggy Windows 11 patch. In March, it had to issue two emergency updates because of installation failures and Microsoft account sign-in problems. Microsoft also released an out-of-band update in July to address an Intel driver issue that was causing performance issues and battery drain.

Editor's Summary Microsoft released an emergency out-of-band Windows update after its record-breaking September Patch Tuesday caused Remote Desktop, USB audio and Hyper-V problems. The fix covers Windows 11 and Windows Server versions, following repeated emergency updates from Microsoft this year.
