Computer Lockout after 15 Minutes of Inactivity - Windows and Mac

Hi @Julie Goyen!

Here is a worklet that you can use for triggering a lock screen after 15 minutes of inactivity on a Windows device,

Evaluation code:

<#
.SYNOPSIS
    Enforce Lock Screen on Inactivity
.DESCRIPTION
	Enforces a Windows Lock Screen after a period of defined inactivity on a Windows device.

.USAGE 
    The only variable to define is the $minutes variable. 
    This is the amount of minutes of inactivity that elapse before the screen locks automatically.
    The evaluation code will check the device to see if the InactivityTimeoutSecs registry key matches the $minutes variable.
    If the value does not match, the device will be flagged for remediation.
    If the value does not exist, the device will be flagged for remediation.
    If the value matches, the device is compliant and the Worklet run will end.

.EXAMPLE
    $minutes = 15
    Device screen will lock after 15 minutes of inactivity.

    If ($exists -eq $timeout)
        {
            Write-Output "Device is compliant. Now exiting."
            Exit 0
        }

    Else
        {
            Write-Output "The Inactivity Timeout registry value does not exist or is not equal to $minutes minutes. Flagging for remediation."
            Exit 1

Remediation code:

    $minutes = 15
    Device screen will lock after 15 minutes of inactivity.

try
    {
        Set-ItemProperty -Path $regPath -Name $regName -Value $timeout
        Write-Output "Successfully set the screen Inactivity Timeout to $minutes minutes."
        Exit 0
    }

catch
    {
        Write-Output "Failed to set the screen Inactivity Timeout."
        Exit 0
    }

This worklet evaluates whether a device has the InactivityTimeoutSecs registry key set.  If it does not exist, or if the value does not equal the $minutes variable that is set, it will trigger the Remediation code to set it.

The results of the Worklet remediation code will be stored in your Automox Activity Log:

For your MacOS devices, this Community Worklet might give you what you need!

Have a great day!
