Reversed Function Keys on Microsoft Surface Pro?

Ever found yourself with locked (reversed) Function keys on your Microsoft Surface Pro (or on your laptop)? I mean, if you want to rename a file in Windows Explorer, you highlight the file and press F2 but only the keyboard brightness is changed (normally this happens on the Surface if you press Fn + F2). While in this state, you press Fn + F2 and the file rename then occurs (!).
The main problem to me is that there is one more key to be pressed (and worst of all, it will have to be pressed with the right hand in the Surface Pro).

To revert to "normal" behaviour it's as simple as this: Press "Fn" + "Caps Lock" key simultaneously. For most programs F1 will start opening help (again), F2 will start renaming, F3 searching and so on.

This will work at least on Windows 8.1 and Windows 10.
