How do i capture each time the Operating System OR the Active Window is busy

Question

I am trying to capture Windows system busy, or Active window busy, from the perspective of the end user (typically when the Windows OS or the active Window puts up a Busy Cursor: or to capture when the system is busy). I am trying to do this without having to continually use GetCursor. Is there any way to set up a windows interrupt, such that when the Operating System or the the active Window is busy that and interrupt can be generated? thanks for your help

You could perform monitoring of the ProcessorQueueLength using the Win32_PerfFormattedData_PerfOS_System WMI object. There are various other performance counter, use the perfmon tool to investigate which of these are most useful to you.
