What this check verifies

Entra-registered Windows device is on a build that is no longer supported by Windows Update, so it cannot receive new security patches.

Why it matters

The device is visible in Microsoft Entra ID but is not managed by Intune, and its reported osVersion is not among the currently supported Windows client or server builds. Unsupported builds stop receiving cumulative security updates from Windows Update, leaving any new CVE on the device permanently unpatched.

How to fix it

Enroll the device in Intune (or another patch-management tool), then apply a Windows feature update to bring it onto a supported build. If the device is intentionally retired or out-of-scope, remove its Entra registration so it no longer appears in the directory.

Siemserva flags every tenant where this check fails and, with Senserva Trustworthy AI remediation, can propose a validated fix you approve before it applies.
