  "account": "Microsoft has issued an out-of-band Windows update to address issues caused by its September security patch. The problems affect Remote Desktop, Hyper-V Linux workloads, and some USB audio devices. The September update caused Remote Desktop Services to become unresponsive, shared Windows folders to disappear in some Hyper-V-based Linux environments, and USB Audio Class 1.0 devices to fail in multichannel modes. Microsoft prioritizes the update over the usual Patch Tuesday for businesses relying on remote access or Windows-hosted Linux workloads. The update addresses CVE-2026-62721 for Windows 11 versions 26H1, 25H2, and 24H2, and includes a fix for CVE-2026-85921 in Windows 11 26H1. The Remote Desktop issue is the most disruptive for businesses, as the bug prevents new sessions from being created and interferes with local and remote sign-ins. Additionally, the update fixes host-folder sharing in some Linux virtual machines running on Hyper-V-based technologies and resolves an issue affecting USB Audio Class 1.0 devices in multichannel configurations. However, some USB audio problems linked to the September update remain unresolved, and organizations should test their systems after applying the update.",
