TopWinPrio checks every now and then to see what window is active at the moment. When it finds the one, it gives it higher priority than the usual normal priority. Once this window loses focus, topWinPrio gives the window its standard status back. TopWinPrio is non-intrusive and does not change any settings in Windows. TopWinPrio runs in the background and can be set to start when windows starts, just run it and forget it's there.
