Since Windows has been released, several have installed them on their computers by activating them normally from its servers Microsoft. Still others are looking for "lateral" ways activationof its new operating system companys. So it looks like they finally figured out a way to activate Windows 8.1 using a standard operating system process (KMS activation).
Η Microsoft of course he was not excited about the news and is looking for ways to close the door to pirates who choose not to pay for the operating system.
Keep in mind that Windows 8.1 is available for free to those who purchased Windows 8 but for new Microsoft customers the price starts from 130 euros.
