This was useful to me. You might mention that this info comes from the file "pooltag.txt", which is installed as part of Debugging Tools for Windows.

In my case, I already had a copy of pooltag.txt on my computer, but wasn't aware of its existence until today.

Don't forget the infamous pooltag of:

SavE - Symantec AntiVirus

The above is most likely why you are googling for this information in the middle of the night because Symantec Antivirus has yet again used up too much pool memory causing your Server to become unresponsive yet again.
