Incompatibility with Win32 API Calls

The Real-Time Windows Target kernel intercepts the interrupt from the system clock. It then reprograms the system clock to operate at a higher frequency for running your real-time application. At the original clock frequency, it sends an interrupt to the Windows operating system to allow Windows based applications or any software using the Win32 API to run.

As a result, software that uses the Win32 API cannot be executed as a component of your real-time application. Any software you use to write I/O drivers must not have any calls to the Win32 API.
