Upgrading to Windows 11
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.
If you are using Windows 10, you can determine if your device is eligible for the upgrade using the PC Health Check app or checking Windows 11 specs, features, and computer requirements. If you have an eligible device, open Windows Update Settings and select Check for updates. Once the upgrade is ready for your device, you will see the option to download and install. Commercial customers can utilize Endpoint analytics, Update Compliance, or other tools to assess readiness across their organization. For more information, see Understanding readiness for Windows 11 with Microsoft Endpoint Manager.
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.
