Microsoft has released Windows 11 26H2, an update that primarily extends the support cycle for different editions of the operating system. For users already running Windows 11 24H2 or Windows 11 25H2, the transition to 26H2 is expected to be quick, as the update is described as an activation package rather than a full installation. This update, also known as the "2026 Update," has been available since September 29 and weighs only 173 KB, requiring a single restart. It activates features already present on the system through previous monthly updates. Users who have enabled "Receive the latest updates as soon as they are available" in Windows Update can move to the front of the line for this update. PCs running Windows 10 or Windows 11 23H2 will need to install the 7.9 GB ISO and perform a full installation. ARM machines delivered in 26H1 remain excluded due to a lack of a common base. The 26H2 update includes several new features, such as the ability to reposition the taskbar on any edge of the screen and a reduced version of the taskbar for small screens. The Start menu has received a redesign, offering more customization options, including the ability to choose between different sizes and manage the visibility of different sections. Search functionality has been improved, with the ability to disable web results and display only local content, as well as tolerate typos and show a preview of results. The File Explorer has also been enhanced, with faster opening times and support for additional archive types. AI features have been integrated into Explorer, allowing users to retouch images or summarize documents, though some features require a Microsoft 365 subscription and a Copilot license. Security features have been strengthened, with the kernel removing default trust from cross-signed drivers, and only drivers certified by Microsoft and a whitelist of older models being accepted. Smart App Control is now activated without reinstalling Windows, and third-party password managers can store access keys. Windows Hello now supports external fingerprint readers in enhanced mode. A new restoration feature allows users to revert their PC, applications, settings, and files to a specific point in time. Accessibility features have also seen improvements, including better voice recognition in noisy environments, a customizable magnifier, and enhanced narrator functionality. Multiple applications can now use the webcam simultaneously, and Bluetooth has seen advancements in LE Audio, calls, and reconnection after extended sleep. Windows Update has been optimized to group more fixes and reduce the number of restarts. However, some known issues have been reported, including audio problems with USB Audio Class 1.0 devices, enterprise PCs losing their domain connection, and black screens on Azure Virtual Desktop. These issues are considered mitigated but not completely fixed. The end of support for Windows 11 24H2 is approaching, with Family and Pro editions no longer receiving security updates after October 13, 2026. The upgrade to 26H2 opens a new 24-month support cycle for these editions, compared to 36 months for Enterprise and Education.
