SYMPTOMS

You may receive a STOP 0x00000078 if the NonPagedPoolSize registry setting is more than seven-eighths of physical memory.


RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

  1. Run Registry Editor and open the following key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
    \Session Manager\Memory Management

    NOTE: The above registry key is one path; it has been wrapped for readability.
