Ok, your computer has been idle for 15 minutes and won’t lock itself.
Time for Group Policy to sort this out as it is in keeping with the ISF Best Practices.
In a GPO, select edit and navigate to: User Configuration, Administrative Templates, Control Panel then Display.
Change the four following GPO settings:
- Screen Saver – Select Enabled.
- Screen Saver Executable – Select Enabled and then type “rundll32 user32.dll,LockWorkStation“
- Password Protect the Screen Saver – Select Enabled.
- Screen Saver Timeout – Select Enabled and then type the amount of time you want to lock your computer in seconds. (For example, if you want to lock your computer after fifteen minutes of idle time, type 900)
Link the GPO appropriately.
