Generally, with subprocess call:

* Pass each element in the command line as a separate element in the 
list: ['SchTasks', '/Create', '/SC', 'ONCE', ... &c.]

* Don't use shell=True unless you're running a command which is internal 
to cmd.exe (such as dir, copy, etc.). If you're running anything which 
exists as its own .exe, you shouldn't be using shell=True.
