You're very much welcome, however be advised, in my case that procedure (as well as many others...) made my keyboard work for about one day, then it went crazy again, in even worse fashion. I am convinced that the Win update ****ed up the drivers pretty bad, I've done my best to clean them and reinstall but I can't seem to find a permanent solution. Only the Corsair keyboard is affected now, every other peripheral works fine. This is just so you know the solution might not be permanent, hopefully it is for you. If not, I'd also suggest looking into removing the win update AND delaying it as much as possible (to avoid Windows reinstalling it immediately on restart), I have win 10 home and it seems it's not possible to do without Pro version :/

If you have Win10, check here http://forum.corsair.com/v3/showthread.php?t=175114
