Microsoft is set to cut off Windows Update access for devices that do not install updated digital certificates by May 17 and June 19, 2027. This change will prevent computers lacking these credentials from establishing secure connections to official servers.
Why it matters
The measure is necessary because the digital certificates currently used to authenticate update servers are reaching their expiration dates. Without the required patches, affected devices will be unable to download future software updates through standard channels.
Windows 11 version 25H2 and later include the required credentials, while Windows 11 24H2 requires patches starting in September 2025. Windows 10 and server editions will need updates released from July 2026 to avoid losing automated update services.
The players
Microsoft
Microsoft is a multinational technology corporation that develops the Windows operating system.
The details
Affected devices will retain the ability to boot and run software, though they will lose the ability to download updates through official channels. Users can restore automated services by manually installing the necessary patches retrieved from the Microsoft Update Catalogue.
Timeline
Required patches for Windows 11 version 24H2 will be issued starting in September 2025.
Required updates for Windows 10 and Server editions will be released beginning in July 2026.
The first certificate expiration deadline for legacy platforms is May 17, 2027.
The final certificate expiration deadline for remaining editions is June 19, 2027.
The Tech Race
This move updates the Windows Update server authentication architecture to maintain modern security standards. It replaces legacy certificate systems, ensuring the platform remains fortified against unauthorized access as previous digital credentials reach their end-of-life cycle.
Users will need to ensure their devices receive all pending updates through the standard settings menu before the 2027 deadlines. Those using legacy systems may need to manually download patches from the Microsoft Update Catalogue to maintain secure update access.
The takeaway
Maintaining updated digital credentials is essential for ensuring your device remains compatible with future security patches. Users should regularly verify that their operating system version is current to prevent potential disruptions in software delivery.
