FirstCountMsgQPeeksSleepBadApp is the number of times the program must query the message queue
                                      before Terminal Services decides that it is ill-behaved.
                                      Decreaseing this value will put the program to sleep more often,
                                      using less CPU time.
Type: REG_DWORD
Default data value: 0xf
Range: 0xf - 0xff


MsgQBadAppSleepTimeInMillisec is the number of milliseconds the program sleeps when it is
                                    determined to be ill-behaved. Increasing this value uses less CPU time.
                                    Setting it to 0 disables the sleep.
Type: REG_DWORD
Data value: 0x1 is the default.

                                     before it is suspended again. Decreasing this value uses less CPU time.
