On December 14, 2021, all editions of Windows 10, version 2004 and Windows Server, version 2004 will reach end of servicing. After that date, devices running these editions will no longer receive monthly security and quality updates containing protections from the latest security threats.
The availability of Windows 11 has been increased to an expanded set of eligible devices. We will continue to train our machine learning model throughout the phased rollout to deliver a smooth upgrade experience and provide you with the latest status updates as we increase availability over time.
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. 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.
