I've streamlined the process by removing the need to install python (Apparently some people don't have admin perms at work! Who'd have thought!?)
Basically, if you have any lock-downs stopping you from making yourself permanently "online" then run this script to double press the "num-lock" every 5 mins or so. This will keep your keyboard active even if you're staring into space at your desk.
Literally just download the .bat file anywhere on your windows machine, and double click it.
