The location is a school with computer labs. The workstations login as general student accounts so they stay logged in all day as the same account. Teachers do not want computers going to a lock screen forcing them to have students log back in during the day between classes.
Prior to Windows 10, this GPO worked great. Windows 10 appears to be ignoring the screensaver settings. I have not been able to locate a technical article that shows where the settings are in group policy that Windows 10 will actually apply that controls the screensaver timeout or lock screen timeout.
You can see all the details of the GPO in the attached document.
The GPO settings worked extremely well before the machines were upgraded to Windows 10. Now the screen saver and screen lock time settings are being completely ignored.
