Ensure 'Access Credential Manager as a trusted caller' is set to 'No One'

高レベル 1自動windows

説明

This security setting is used by Credential Manager during Backup and Restore. No accounts should have this user right, as it is only assigned to Winlogon. Users' saved credentials might be compromised if this user right is assigned to other entities. The recommended state for this setting is: No One.
