So... I have a Logitech K270 and when I go to use it in my PC, NOTHING but the media keys work. I'm assuming that it's another janky update for Windows, somehow corrupting or deleting the HID keyboard driver, for when I plug in the receiver, it's recognized AS A MOUSE! I need a solution, because as for a lot of you, PCMR is life, so please leave you suggestions below. Thanks.
