Hi,
They are a function of your keyboard driver software supplied by the
manufacturer. Check the keyboard applet in the control panel, if there is
any means of disabling the notifications it should be found there.
Otherwise, you would need to uninstall the supporting software and revert to
a standard keyboard driver.
