When a program causes a problem, in many cases an exception code is build by Windows to identify the nature of the fault. Use the Exception Solutions index to find information on a specific exception.
Faults occur when programs perform an action that is not recommended (a warning) or one that is not allowed (an error that is usually fatal). For example, if a program attempts to access protected memory, Windows will stop the program from running to protect the rest of the system and ensure a higher level of security.
This decoder helps split apart the the 32-bit NT status exception code into its functional parts and describes what each part of the code means. The code structure also allows for application vendors to create their own exception codes, which are not documented.
