That's especially ridiculous because this whole security mechanism that Microsoft is forcing on Windows user doesn't even work. There are tons of leaked certificates and on forums dedicated to game hacking you can find guides on how to get your hands on one yourself. People there use them to write kernel drivers for cheating in games. Game developers often blacklist these in their anti-cheat software so that the game no longer launches on a computer using a driver with that certificate. Microsoft however does not do this and malware developers can then simply use the certificates for their own purposes. So all this nonsense is basically just a restriction on regular users and honest developers while the “bad guys” can get around it.
