  • PoolTag - setting the value to 0x2a
  • PagedPoolSize - setting this value to 0x10000000
Note: PagedPoolSize is only modified on 32-bit Windows Server 2003 Operating Systems

On operating systems newer than Windows Server 2003, Special Pool setting runs verifier tool to enable pool tagging. In this case, the following registry values under 'HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management' are modified:
  • VerifyDrivers - setting the value to *
  • VerifyDriverLevel- setting this value to 0x1
After running the package, you will be prompted to enable Special Pool. If you accept, the settings above will be modified. The diagnostic package will prompt you to reboot. After rebooting Special Pool will be enabled.

You can run the diagnostic package for a second time to disable Special Pool and return the original configuration.
