Microsoft has started force installing Windows 11 23H2 on eligible devices that have reached or are close to their end-of-servicing date.

The Windows 11 23H2 forced rollout phase announced by Redmond this week comes after systems running multiple editions of Windows 11 21H2 were automatically updated to Windows 11 22H2 before they reached the end of support on October 11.
