Make Win key + numpad numbers work

Question

It's possible to use Win Key + a number to switch between pinned programs as described in this question

I find that it would be more convenient to use the numpad numbers, but it does not work. (tried switching with num key).

Is it possible on Windows 7?

Answer 1

In the end I could only remap them using AutoHotKey:

#Numpad1::
send, #1
Return

#Numpad2::
send, #2
Return

etc...
