How to enable windows keys (pg up/pg down) on apple wireless keyboard on PC

Not very development related question but still.

I have PC + Windows 7 + Apple wireless keyboard. Struggling to find a way to have pg u开发者_如何转开发p/pg down or home/end functionality out of it. No luck so far. Any suggestions?

The way keys work on a Mac for that functionality is:

fn + up arrow key -> page up
fn + down arrow key -> page down

command + left -> front of the line
command + right -> end of the line

This will also depend on if key mappings are set up correctly.
