Q: I am using an Apple keyboard with numeric key pad.

I would look for a program which would display the ascii value of typed letters

if i had the letter the key send one can assign that value to any other function one wish

if the program would get no ascii value from the num keyboard then I suppose ms were correct

if not then there are tons of free programs to reassign keys as one see fit

and even if they were not to work one can do it manually in regedit in windows

Make sure mouse keys are turned off on the Mac side AND Windows side - Control panel > ease of access > ease of access center > then click "make the mouse easier to use" (in Windows 8.1).
