Open it in Notepad. Search for your tag. You might see:

Introduction: What is PoolMon.exe? In the realm of Windows system administration and advanced troubleshooting, few tools are as revered—and as misunderstood—as PoolMon.exe (Pool Monitor). This command-line utility, part of the Windows Driver Kit (WDK), provides a real-time, bird’s-eye view of the Windows kernel memory pools: Paged Pool and Non-Paged Pool . Open it in Notepad

In an era where cloud dashboards and colorful GUIs dominate, PoolMon stands as a testament to the power of raw data. Its columns of hexadecimal and cryptic tags reveal the hidden life of kernel memory. On Windows 7—a platform that refuses to die in embedded systems, medical devices, and legacy workstations—PoolMon is often the only tool that can save you from a weekend of random crashes. This searches all driver binaries for that string

Download the Sysinternals Suite (easiest) or the WDK 7.1.0 (most official). Run poolmon -b -d regularly. And when you see that one tag ballooning to gigabytes of non-paged pool, you’ll know exactly which driver to blame. Disclaimer: Windows 7 reached end of life on January 14, 2020. Microsoft no longer provides security updates. Use PoolMon and diagnostic tools only on systems that are isolated from the internet or as part of a controlled migration plan.

Ntfs - ntfs.sys - NTFS filesystem driver For stubborn tags, attach the Windows 7 kernel debugger ( kd.exe from the WDK) and use !poolused or !findpool commands. This is advanced but definitive.
