Each working program has its priority. Windows kernel priority is
highest, other programs work with normal priority. Why? We may increase
any program´s priority not loading processor! When you change windows,
PC Acelerate automatically increases foreground window priority
(programs shortcut you see in system tray). Except this if free PC memory
will decrease (after unloading a program from memory can remain already
not working libraries), PC Accelerate preventive will unload them from
memory in that moment, when you work more intensive and will support
the free-memory volume on constant average level.
