system_thread_exception not handled in windows

I always hear about the system_thread_exception not being handled in Windows OS - what is the essence of this problem, and how can we avoid it? Also, why is this problem Windows-specific?

Solution

  • SYSTEM_THREAD_EXCEPTION_NOT_HANDLED is the bug check 0x7e:

    The SYSTEM_THREAD_EXCEPTION_NOT_HANDLED bug check has a value of 0x0000007E. This bug check indicates that a system thread generated an exception that the error handler did not catch.

    ...

    Cause

    The SYSTEM_THREAD_EXCEPTION_NOT_HANDLED bug check is a very common bug check. To interpret it, you must identify which exception was generated.

    Common exception codes include the following:

    • 0x80000002: STATUS_DATATYPE_MISALIGNMENT indicates an unaligned data reference was encountered.
    • 0x80000003: STATUS_BREAKPOINT indicates a breakpoint or ASSERT was encountered when no kernel debugger was attached to the system.
    • 0xC0000005: STATUS_ACCESS_VIOLATION indicates a memory access violation occurred.

    To avoid this, read about Handling Exceptions for how driver developers should write code that properly handles exceptions. Is it Windows specific since we're talking about windows drivers development and kernel BSOD codes.
