How do I turn in a software pirate to Microsoft? I have a roommate that has a pirated/unpaid for version of Windows 7 Ultimate on his pc. Person, is starting to be a pain & and payback is a bitch. Especially, when it comes from a non-thief, that pays for everything he has. I let him on my network, just long enough to get his computer name on my Windows 10 Pro pc and my router's website. I then booted his pc off and blocked it. I let him know that he needs to get his own network service.
