People in these countries were as a result required to choose a system setting inconsistent with their localised version of English, thereby causing traditional British English to fall out of favour.

Other keyboard layouts
Other operating systems can optionally re-map the keyboard layout or have different modifier keys (for example the Amiga keyboard has "A" modifier keys and BBC Micro or Acorn keyboards often had a "Shift Lock" as well as a "Caps Lock").
Under Unix/Linux the "Windows" key is often called the "Super" key and can be re-mapped by users for specific functionality but in most programs by default does nothing.
Some older Unix/Linux software, such as Emacs, uses the left Alt key as a "Meta" key, which harks back to older MIT or LISP computers.
