Windows 11 release information

Windows 11 will have an annual feature update cadence. Windows 11 feature updates will release in the second half of the calendar year and will come with 24 months of support for Home, Pro, Pro for Workstations, and Pro Education editions; 36 months of support for Enterprise and Education editions.

We recommend that you begin deployment of each feature update promptly to gain access to new features, experiences, and integrated security as soon as possible.

For monthly security updates, Windows 11 uses the familiar Windows cumulative update process, also referred to as a "B" release, Patch Tuesday, or Update Tuesday. These monthly releases will continue to contain all previous updates to keep devices protected and productive.
