Windows 10 has introduced several new networking issues.
It can be difficult to find and shutdown all the firewall options and network "helpers".

How you handle the Motor Safety will depend on the language you use.
There will be a call to set the interval, but by default it'll be 0.1 sec.
How the motor safety works is simply if subsequent Set motor calls aren't made within that 0.1 sec, then the PWM output automatically gets set to neutral.
If your code just calls the Set Motor constantly no matter what, then it'll defeat the purpose of the safety.
