Consider the following scenario:

  • You start an application that monitors registry settings and identifies when registry entries are┬áchanged on a computer that is running Windows 8 or Windows Server 2012.

  • The application uses the ZwNotifyChangeKey routine in synchronous mode.

  • You try to shut down the computer.

In this scenario, the computer crashes, and you receive a Stop error message that resembles the following:

Stop 0x0000007E (parameter1, parameter2, parameter3, parameter4)


  • This Stop error describes a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED issue.

  • The parameters in this Stop error message vary, depending on the configuration of the computer.

  • Not all the "Stop 0x0000007E" errors are caused by this problem.


This issue is caused by a race condition.
