I copied the tables from [WayBack] Memory Performance Information (Windows) as even Microsoft managed to let information “disappear” for EOL products (the en-US version already “disappeared”):
System Memory Performance Information
The following table associates memory object performance counters with the data returned by the memory performance functions in the MEMORYSTATUSEX, PERFORMANCE_INFORMATION, andPROCESS_MEMORY_COUNTERS_EX structures, and with the corresponding information displayed by Task Manager.
