Symptoms


When you run an application that uses the RegSetValueEx function on a computer that is running Windows 7, Windows Server 2008 R2, Windows Vista or Windows Server 2008, the computer may crash. Additionally, you may receive a Stop error that resembles the following:
Stop 0x00000050 (parameter1, parameter2, parameter3, parameter4)

PAGE_FAULT_IN_NONPAGED_AREA


Notes
  • The parameters of the Stop error message vary, depending on the configuration of the computer.
  • Not all "0x00000050" Stop errors are caused by this issue.

Cause


This issue occurs because of an error in the audit component. When you set the security policy as audit and then change the registry key, the audit component does not correctly handle registry strings that are non-null terminated. Therefore, you receive the Stop error message.
