F1 & F12 shortcut not working

Like the title says, my F1 & F 12 shortcut is not working in X7 using Windows 10, I'm guessing it has something to do with Windows 10. It will work with Fn & F12 keys together. I have tried a repair in X7. I'm using a new Dell Inspiron 5000 series. It works normal on my Windows 8.1 machine.

Thanks

Mike
