so Windows updated last night just before I turned of my computer and when I turned it on this morning my mouse wasn't working, mouse is a steel series kinzu v2, I had no problem at all with it prior to this update, I tried a system restore to before this update and it still won't work, I've also tried starting my PC in safe mode and it still won't work, the mouse is lighting up each time like it is working, I'm out of ideas and I can't afford to get another mouse. Come one people, I need answers....
