WN12-UC-000001 - A screen saver must be enabled on the system.

Information

Unattended systems are susceptible to unauthorized use and must be locked when unattended. Enabling a password-protected screen saver to engage after a specified period of time helps protects critical and sensitive data from exposure to unauthorized personnel with physical access to the computer.

Solution

Configure the policy value for User Configuration -> Administrative Templates -> Control Panel -> Personalization -> 'Enable screen saver' to 'Enabled'.
