Q:

Media keys won't work unless certain programs are selected

I just bought a Corsair Vengeance K70 which comes with four media keys: stop, skip (forward and backward), and play/pause. The problem is they don't work. I can only use them when either the Services window (through Computer Management, Task Manager, or services.msc, Curse Voice, Logitech Gaming Software, or Gigabyte Force is open and the selected window.
My HID Service is set to Automatic (Trigger Start) and is running. Media keys also don't work when the HID service is disabled.
I've tried closing all open programs as well as unplugging all extra hardware, none of which helps. I've also tried different USB ports.
This is also after a fresh install of Windows 7. Any ideas?
Programs confirmed to work:

Ccleaner
Computer Management
Gigabtye Force
Logitech Gaming Software
MSI Installers
Services
Task Manager

A:

Turns out the Google Music Chrome extension was the cause of this.
Case closed.
