Organizations using Microsoft Intune are facing an issue where a bug has caused unexpected upgrades to Windows 11, despite settings to block such updates. This problem has been acknowledged by Microsoft and has been present since April 12, affecting only devices managed through Intune. Microsoft is working on a resolution and recommends pausing all Windows feature updates via Intune. For devices that have already upgraded to Windows 11, organizations can either adapt to the new system or manually revert to Windows 10, as there is no automated rollback method provided by Microsoft. The manual process involves creating a bootable Windows 10 device and performing a fresh installation.
