You can’t feed flightaware via Windows… And soon you won’t be able to feed FR24 either via Windows.
You could just install Linux on the box or even run an USB-stick linux (Anyone working with the new x86 Raspbian - #232 by abcd567)
If you just want the local display i believe there are windows applications for that too.
For example virtual radar server should work http://www.virtualradarserver.co.uk
Oh and you seem to be confusing flightaware and flightradar24
