MATLAB should display a message similar to
Real-Time Windows Target version 2.5.0 (C) The MathWorks, Inc.

MATLAB performance = 100.0%
Kernel timeslice period = 1 ms
Once the kernel is installed, you can leave it installed. After you have installed
the kernel, it remains idle, which allows Windows to control the execution of
any standard Windows application. Standard Windows applications include
internet browsers, word processors, MATLAB, and so on.
It is only during real-time execution of your model that the kernel intervenes
to ensure that your model is given priority to use the CPU to execute each
model update at the prescribed sample intervals. Once the model update at a
particular sample interval completes, the kernel releases the CPU to run any
other Windows application that might need servicing.
