Here's what i can tell you in-depth.
My OS is windows 8 64 bit.
I'm pretty sure another keyboard won't change anything.
The last piece of info you might want to know is there's this screen keyboard by microsoft in "Ease of Access Center" which works for me, i can use the tab key, 'w' key, and windows logo key on there.
However when i press down these keys on my physical keyboard nothing happens; no shortcuts...nothing.
