Of course not ALL keyboards are laid out the same way, even the so called QWERTY keyboard.
Many countries have different or extra letters in their alphabet and therefore some keys are in different places on their keyboards.
Also often special characters (ie backslash) are in different places on a keyboard which can cause confusion when going abroad.
The hardest I ever used was a Japanese keyboard, never again.
Of course one of the settings in Windows is the country type of the keyboard so Windows knows what to type when the keys are pressed.
