In principle this keyboard is compatible with Windows, BUT the keyboard does not work 100% as expected. For example, the OPT and CMD keys, which are normally WIN and ALT on other logitech keyboards, are reversed when using the keyboard in windows mode. This means that CMD which is next to the "SPACE" key is actually the WIN key and not ALT! Unacceptable for Gamers and Excel-Freak. Even if you use Powertoy, it doesn't always work with more complex key combinations.

As I wanted a white keyboard but for windows, I bought the black MX Mechanical Mini version and exchanged the PCB. with the white keyboard.

Also the Mac version does not have the function to switch between MAC and Windows. The keyboard is always in "MAC" mode...in my opinion for the same price you have less options with this keyboard. Except for the colour!
