He insists that keyboard can be only one that has a 3rd. key for windows. The key is red.
I have never heard of a keyboard with a red Windows key.
The only Windows keys that I know of are the two that are down near the spacebar or Alt keys on modern keyboards.
When I did a Google search, I found pictures of reddish labels with Windows activation keys on them, like ***this***
. I wonder if there isn't some confusion about the type of key Windows needs -- keyboard key vs. activation key.
