  1. Yes microsoft keeps moving zillions of IP-Addresses and is not allowing us control over our Windows machine so that we have no way of stopping big brother from force feeding us updates and other spyware junk.

    My personal PC does not feel personal anymore and my firewall does not have the room for me to enter all the addresses that i want to block and to be honest i don’t have the time

    This MCSD wants to jump ship and it’s high time that our bent politicians who are all on the take past a privacy bill that had some real teeth
