Microsoft has acknowledged a bug affecting some Windows 10 users, incorrectly notifying them that their systems are “out of support.” Users can extend their Windows 10 support at no cost until October 13, 2026. The misleading message appears even when the user’s PC remains fully supported. This issue potentially impacts users on Windows 10 Pro, Enterprise, Education editions with ESU enabled, as well as Windows 10 Enterprise LTSC 2021 and IoT Enterprise LTSC 2021. Users will continue to receive updates if they are on Windows 10 LTSC or linked to ESU. Microsoft is rolling out a server-side fix for the false alert, which is expected to disappear within 24 to 48 hours. Users can verify their installed version or edition by navigating to Settings > System > About. Microsoft has provided a rollback option for IT administrators to address this issue.
