Windows 11 26H2 is now rolling out. Microsoft officially released the Windows 11 2026 Update on September 29, 2026, and eligible Windows 11 PCs can receive the new version through Windows Update.

For users already running Windows 11 24H2 or Windows 11 25H2, the upgrade is considerably smaller than a traditional Windows feature update. Microsoft uses an Enablement Package called KB5121794 that activates components already delivered to the PC through previous monthly updates.
