WN25-00-000480 - Windows Server 2025 must be maintained at a supported servicing level.

Information

Systems at unsupported servicing levels will not receive security updates for new vulnerabilities, which leave them subject to exploitation. Systems must be maintained at a servicing level supported by the vendor with new security updates.

The Long-Term Servicing Channel (LTSC) remains the standard support branch for Enterprise server platforms. The guidance in this rule assumes usage via this support channel.

Solution

Determine if the end-of-support date for the system's OS build (e.g., build 26100.xxxx) is a past date.
If the end-of-support date for the system's OS build is in the past, perform an update to an OS build with a future end-of-support date.
