I am already running cmd.exe with the highest privilege. Why am I still denied access?
Other commands like sc queryex works just fine.
I have not tried using the sc config on other services yet. Didn't want to mess too much with things when I don't yet know what's going on.
I am running Windows Version 6.3.9600 (Windows 8.1)

The Task Scheduler is an essential system component and as such is protected from some manipulations.
I do not understand why it is necessary to configure it for auto-start. It should already be set this way. The fact that you are having troubles configuring it means that it is already running.
If you are just practicing on using the sc config command, I suggest trying
it on a less important service. Verify by
opening the Services applet, right-click the service and check that not all actions
are grayed-out.
Although not recommended,this threadhas an answer on how to disable such a service so it may be configured. I do not recommend it, as Windows boot might malfunction.
"SC OpenService Failed Access is denied" error when using an sc config command.
Looking at your second screenshot, it looks like you are trying to change the configuration of a running service.
Try stopping the service first and then restarting it after you have changed the configuration.
Some options only take effect at the point when the service is started e.g. the SC config command allows the executable of a service to be changed. When the service next starts up it will run the new executable. Config changes requires the current user to have “permission to configure the service”.

1Looks like Windows protects some services configuration from changes. It doesn't matter whether the service is running or not. I tried disabling Windows Store service and failed the same way:
sc config WSService start=disabled
Access is denied.But at the same time I could do it by editing registry:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\WSService\Start=4
