Windows 11 2026 Update released, here's everything you need to know
Microsoft has released the Windows 11 2026 Update (26H2), which is an annual feature update delivered as a small enablement package for devices already running Windows 11 24H2 or 25H2. This update shares the same servicing branch and source code base as previous versions, meaning most features have been gradually introduced through monthly updates rather than being exclusive to 26H2. Devices running Windows 11 26H1 cannot upgrade directly to 26H2 due to a different Windows core. The update resets the Windows support lifecycle, providing 24 months of support for Home and Pro editions and 36 months for Enterprise and Education editions. There are no new security vulnerabilities or exploits associated with this update mentioned in the source content.
