True
>>> sysproxy.daemon_off() # Turn proxy daemon off.
True
>>> sysproxy.daemon_on_() # Turn proxy daemon on. You should launch this function in a Python thread.

sysproxy daemon

When sysproxy daemon turned on, it executes a window-less WINAPI event loop that captures WM_QUERYENDSESSION message, which is sent when Windows is about to shutdown. When the message arrives, the daemon calls off(), which turns proxy settings off.

As mentioned above, sysproxy.daemon_on_() will block current Python execution, so you should launch it in a Python thread.
