(11.2.x) -- Is there a command to get the Zenworks agent to log out, and also
one for logging in, at the Windows workstation? e.g. a command-line equivalent
to right-clicking the icon in the system tray area & choosing "Logout" or "Login".

I'm sure if there is, it's somewhere obvious in the documentation, but I
haven't been able to find it. So far the only way I can see to cause a logout
is to remove the registry entries that cache the current username.
