If the Vulnerablility Scan result is displayed as Unscannable, you can select the corresponding item to see the reason for the check not possible in the detailed information of the check item.

Common reasons for an Unscannable result in the "OS and MS Office are up to date with latest security patches" check are as follows.

If EPM is linked but patches have not been applied in EPM

Although it is set by administrator policy to receive security patches through EPM (EPP Patch Management), if EPM has never been run, it may be displayed as Unscannable.

Right-click the EPP tray icon, then run EPP Patch Management to proceed with the patch check.

If there is a problem receiving Windows updates

In environments not linked with EPM, security patches are applied using the system's Windows Update feature.

If Windows Update cannot be received properly due to network errors or system errors, this item may be displayed as Unscannable.

Please check if updates are proceeding normally in [Settings] - [Update & Security] - [Windows Update].
