Hi Walter,
Thanks for reaching out!
While many praise this keyboard it is quite outdated in terms of it's compatibility with newer windows as it was designed for Windows XP and older.
Here's the datasheet for your reference.

Are you trying to use it with the original PS2 connection or a USB converter? I saw another thread where someone details that "My Documents, My Pictures and My Music" keys won't work. So if that's what you're looking for don't know if you can make them work.
I will link the discussion to another page on the MS forum where you can read more about this. Someone suggests adapters to USB but I cannot promise nor take responsibility if that will not work either.
