Microsoft has unveiled the Windows 11 2026 Update, version 26H2, on September 29, 2023, accessible for eligible devices running Windows 11 versions 24H2 or 25H2. The update is a controlled feature rollout and is delivered as an enablement package, activating features already embedded in the system. It consolidates improvements, security patches, and enhancements from the past year, with some features previously disabled in 25H2 now enabled by default in 26H2. Installing 26H2 resets the support lifecycle, providing 24 months of support for Home and Pro editions and 36 months for Enterprise and Education editions. Users can manually request the update through Windows Update settings. Organizations can deploy 26H2 via Windows Autopatch and other management tools, with targeted deployments recommended first. Devices that shipped with Windows 11 version 26H1 cannot upgrade to 26H2 and will receive a future upgrade path instead. Microsoft may also implement safeguard holds on devices with known compatibility issues.
