Keyboard recognized as natural

Hi everyone!
I have a Chiconey multimedia keyboard on an XP SP2 computer
Everything was working fine, but I now can't execute any windows shortcuts (for example, the Windows+R for run), I even can't press Enter to get to a new line while printing a text document.

I tried changing the layout, it's correct and I'm sure.
The keyboard is listed in device manager as: Windows Standard Keyboard or Windows Natural Keyboard

Could this be the problem? I uninstalled the keyboard, rebooted, and it's the same.

 

I have an AZERTY keyboard but because i work in English and my keyboard is for Belgium i have the setup for the keyboard to "Belgium point" if i try to set it to English a lot of the keys are misplaced.
i don't know if yours is a location problem but always worth a look.

Mine is QWERTY
It was working with the same settings, this is why I'm confused!
