Microsoft has initiated the rollout of an emergency out-of-band update aimed at rectifying several issues stemming from its extensive September Patch Tuesday update. This monumental update, which addressed nearly 1,000 vulnerabilities, inadvertently introduced a series of bugs impacting various sectors, including businesses, developers, and gamers.
The September update specifically disrupted functionalities related to folder shares on Hyper-V-based Linux virtual machines, Remote Desktop Services sessions, and certain USB audio devices. In response, the newly released out-of-band update targets these concerns across multiple versions of Windows 11, namely 26h1, 25H2, and 24H2. Additionally, updates have been made available for Windows Server 2025 and 2022, as well as the LTSC versions of Windows 10 and Windows Server 2012 and 2012 R2.
Historically, Microsoft has been cautious about issuing out-of-band updates for Windows; however, this practice has become increasingly prevalent in 2023. Earlier this year, the company found it necessary to release four out-of-band updates in January due to issues arising from a problematic Windows 11 patch. March saw the issuance of two emergency updates to address installation failures and Microsoft account sign-in complications. Furthermore, in July, an out-of-band update was deployed to resolve performance issues and battery drain linked to an Intel driver.
