Windows notices inactivity of a logon session, and if the amount of inactive time exceeds the inactivity limit, then the screen saver will run, locking the session. The recommended state for this setting is: 900 or fewer second(s), but not 0. Note: A value of 0 does not conform to the benchmark as it disables the machine inactivity limit. Rationale: If a user forgets to lock their computer when they walk away it's possible that a passerby will hijack it. Impact: The screen saver will automatically activate when the computer has been unattended for the amount of time specified. The impact should be minimal since the screen saver is enabled by default.
To establish the recommended configuration, set the following Device Configuration Policy to 900 or fewer second(s), but not 0: To access the Device Configuration Policy from the Intune Home page: Click Devices Click Configuration profiles Click Create profile Select the platform (Windows 10 and later) Select the profile (Custom) Enter a Name Click Add Enter the Details below Name: <Enter name> Description: <Enter Description> OMA-URI: ./Device/Vendor/MSFT/Policy/Config/LocalPoliciesSecurityOptions/InteractiveLogon_MachineInactivityLimit Data type: Integer Value: 900 or fewer, but not 0 Select Save Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.) Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy. Default Value: 0 seconds. (There is no inactivity limit.)
