What does Windows error code 696 (ERROR_DBG_CONTROL_BREAK) mean?

ERROR_DBG_CONTROL_BREAK

What ERROR_DBG_CONTROL_BREAK means

The debugger received a Ctrl+Break control event. In practical terms, this status belongs to console break handling: a stronger console break signal reaches the debugger and may bypass ordinary Ctrl+C expectations.

Typical causes

• A user pressed Ctrl+Break
• A management tool generated CTRL_BREAK_EVENT for the process group
• The debugger is configured to stop on console break notifications

How to investigate

1. Record the target process group and event timestamp
2. Inspect debugger policy for passing or swallowing Ctrl+Break
3. Verify whether the program has a console control handler for graceful shutdown

Developer guidance

Ctrl+Break often indicates an operator request for interruption, but the final behavior depends on debugger continuation and the application handler.
