When using Server 2012 I disabled the (evil) Automatic Maintenance task using the following commands (originally found here):
psexec \\SERVERNAME -s schtasks /change /tn "\Microsoft\Windows\TaskScheduler\Maintenance Configurator" /DISABLE
psexec -s schtasks /change /tn "\Microsoft\Windows\TaskScheduler\Maintenance Configurator" /DISABLE
When I try to run this on Server 2016 those entries do not exist. I know it is somewhere because TiWorker.exe eats up a bunch of CPU doing whatever it does. Does anyone know where this setting is in Server 2016?
