  4. Use the kdex2x86 extension to dump non-paged pool, and then select a non-paged pool memory address to sample. In this example, 81457000+8000 (which is 8145f000) was used:
    1: kd> !kdex2x86.xpool -map

  5. Run the !pool 8145f000 command on the sample.
  6. Confirm through several samples that the DAP4 tag is consuming non-paged pool.
  7. Run the !drivers command to confirm the date of the driver:
