Raw Input Alternative Keyboard Hook?

Question

Quick question -

I read about keyboard hooks and suggested using Raw Input for this, but I did not find any example. For example, I use

RAWINPUTDEVICE rid[1];
rid[0].usUsagePage = 0x01;
rid[0].usUsage = 0x06;
rid[0].hwndTarget = hWnd;
rid[0].dwFlags = 0;
RegisterRawInputDevices(rid, 1, sizeof(rid[0]));

And catch WM_INPUT in its own application window, but not outside the application. Is this possible outside the application or do you need to use WH_KEYBOARD or WH_KEYBOARD_LL? MSDN did not make it clear whether Raw Input can be done globally.

EDIT: I know about Hooks, but I want to know if you can do this using Raw!

Greetings
