Windows XP and Windows Vista does not contain a keyboard layout for the UK version of the Apple Pro Keyboard. This small utility installs a Windows Keyboard Layout (KBD) file into the operating system that replaces the current layout with one that matches the Apple Pro Keyboard so you can use it with Windows. This changes the keys so the keystrokes you make will match the legends on the keytops. So pressing Shift-2 will insert the @ symbol instead of the " symbol. The new layout can be enabled from the Regional and Language Options control panel. This new layout only modifies the main keyboard keys, the numeric keypad and other keys are not modified in any way. Version 2.0 adds 32-bit and 64-bit Windows XP support and 32-bit and 64-bit Vista support.
