Microsoft has started rolling out the Windows 11 2026 Update. This update brings a refreshed support lifecycle and improvements focused on security, management and usability.
Unlike previous major Windows upgrades, 26H2 is designed to be a low-disruption update. Many eligible devices running Windows 11 24H2 or 25H2 can upgrade through a small enablement package that installs quickly and normally requires a single restart.

Windows 11 26H2 may not be packed with headline-grabbing new features, but it delivers a more polished and mature Windows experience. With improvements to security, management, productivity and core Windows functionality, the update helps organisations stay secure, supported and ready for the latest Microsoft technologies without disrupting day-to-day operations.
- Enhanced security and device management capabilities.
- Improvements to File Explorer navigation and usability.

Businesses using Microsoft Intune, Windows Autopatch or other managed update solutions should review their update policies now to ensure devices remain compliant and fully protected.
