My brother constantly spams away on the internet, not giving a stuff about anyone else, and draining our very limited downloads. I try to tell him not to, even try to get Dad to stop him, but alas nothing works, one reason being "I can't prove anything."

To circumvent this I've installed a program onto all of our computers to monitor how much we download so if suddenly we're way over our limit, I can say look this is how much x y and z have downloaded therefore they're the one abusing our internet. However my brother, being completely and utterly irresponsible, does not care for this, and spams away downloading videos and whatnot, completely disregarding the fact Dad and I NEED THE INTERNET for our online courses, and if the speed gets dropped down then it's very hard for us to do so.

He has figured out (which most tech-savvy people would see as common sense) that if he closes the process or ends the service (regardless if he closes one the other closes also) then his usage won't be monitored and he'll keep on getting away with it.

I need to know how to stop him from being able to close the process. I know it can be done because our school's got it on other various processes/services. I've already tried a number of things including group policy, editing permissions, and tweaking the registry, however none of these solve the problem. Google suggests I use a program such as one written in VB to solve the issue - however my VB skills are limited and the VB solutions which actually give the code do not stop the user from ending one process, they stop the user from ending all processes.

Any help on this would be greatly appreciated.
