Debug system error codes

System error codes can occur across many locations in the system and require investigation and analysis to debug (due to their scope, descriptions for system error codes cannot be very specific), starting with the programmatic and runtime context in which the errors occurred.

System error codes are defined in WinError.h and can be returned by non-system software or by a function deep in the stack and far removed from code that is handling the error.
