When an application tries to open large files (over 100MB), the open request may fail with one of the following error messages:

Insufficient Resources

- or -

Invalid Handle

The actual error returned varies depending on the application being used to open the file.


The allocation for paged-pool memory was modified to correct any problem that might occur on systems that have large files (greater 100MB) that are repeatedly opened sequentially, updated, and then closed.

Ntoskrnl.exe and Ntkrnlmp.exe have been updated to correct this problem.

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.

  1. Start Registry Editor, locate and select the following Registry subkey in the HKEY_LOCAL_MACHINE subtree:

          \Session Manager\Memory Management

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

  2. From the Edit menu, click Add Value.
  3. Enter DisablePagedPoolHint as the value name and set the Data Type to REG_DWORD.
  4. Click OK and enter 1 as the Data.
  5. Click OK, quit Registry Editor, and then shut down and restart the computer.
