DBG_EXCEPTION_HANDLED

The debugger consumed the exception

This status is a debugger continuation decision, not the original exception code. It tells Windows that the debugger accepted responsibility for the exception reported in an EXCEPTION_DEBUG_EVENT. The system therefore resumes the stopped thread without continuing the normal search for a structured exception handler in the target process.

A debugger should return this result only after it has deliberately handled the event, such as a breakpoint it inserted itself. Marking an access violation or other application exception as handled can hide the fault and resume execution with invalid state.

What to inspect

Record the original exception code, address, first-chance flag, process ID, and thread ID before continuing.
Verify that the exception belongs to the debugger, rather than to the application or a runtime handler.
Check whether instruction pointer or register state must be adjusted before the thread resumes.
Do not interpret the status as proof that the underlying program defect was repaired.
