If your existing Windows 10 PC is running Windows 10 20H1 or later and meets the minimum hardware specifications it will be able to upgrade to Windows 11. The upgrade rollout plan is still being finalized, but for most devices already in use today, we expect it to be ready sometime in early 2022. Not all Windows 10 PCs that are eligible to upgrade will be offered to upgrade at the same time. To see if your PC is eligible to upgrade, refer to the specifications here. Once the upgrade rollout has started, you can check if it is ready for your device by going to Settings/Windows Updates. Similar to how end users are notified when updates are available in Windows 10, end users will see an indication in the notification areas of the taskbar in the bottom right, that the upgrade is available. More information on how that is presented will be available at a later date. Additional desktop notification options may be also be added at a later date.
