Stop error when a registry management problem occurs on a Windows Server 2008 or Windows Vista SP1-based computer: "0x0000007E"

This article has been archived. It is offered "as is" and will no longer be updated.
Not sure if this is the right fix? We've added this issue to our memory dump diagnostic which can confirm.
On a computer that is running Windows Vista Service Pack 1 (SP1) or Windows Server 2008, you receive the following Stop error message:

  • The first parameter is 0xc0000005. Other three parameters in this Stop error message may vary, depending on the configuration of the computer.
  • Not all "0x0000007E" Stop error messages are caused by this problem.
Additionally, the following event is logged in the System log:

Source: Microsoft-Windows-WER-SystemErrorReporting
Event ID: 1001
Task Category: None
Level: Information
Keywords: Classic
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007e (0xc0000005, <address>, <address>, <address>). A dump was saved in: <file path>.

This problem occurs because the registry management module does not manage mapped views in memory correctly. Therefore, a view is freed even though it is being mapped. Any access to this freed view will cause the system to trigger stop code 0x0000007E.
