They use the same industrial computers ands real-time OSs that modern airliners use, and which Nasa uses on more modern kit. The shuttle software isn't necessarily a good engineering solution.Spending the same time/effort/budget on a more critical part might have saved some of the shuttle failures. If you think of it in aircraft terms, is it better to spend $ making the avionics software 99.9999% reliable rather than 99.999% or is it better to fit smoke hoods/more exits/better weather radar etc.
