Microsoft has released an emergency out-of-band update to correct problems introduced by its September Patch Tuesday release, which fixed nearly 1,000 vulnerabilities but broke folder sharing on Hyper-V Linux virtual machines, disrupted Remote Desktop Services sessions, and caused issues with some USB audio devices. The new fix covers Windows 11 versions 26H1, 25H2, and 24H2, along with Windows Server 2025, 2022, and 2012 R2, plus LTSC editions of Windows 10.

Microsoft has pushed emergency out-of-band updates for Windows 10, Windows 11, and Windows Server to resolve Remote Desktop Services instability caused by its September 2026 security patches. The bug had triggered RDP sign-in failures, unresponsive servers, and related issues in MMC, File Explorer, and the Windows Update page. Separate fixes for the update also address Hyper-V and USB audio problems reported on some Windows versions.

Microsoft confirmed that starting in October 2026, memory integrity protection built on Virtualization-based Security will be switched on by default for eligible Windows 11 PCs. The feature runs Windows as a guest OS under Hyper-V to isolate the kernel from tampering, but Microsoft has previously acknowledged it can hurt gaming performance. Organizations will retain the ability to disable it, though the default posture is shifting toward security-first.
