Techwiki:Performance Counter Indexes

This information was compiled by dumping the Performance Registry Text and Help Text hives and then crosslisted with Technet's documentation on Windows 2003 performance counters. The primary issue with the listings provided in the Text hive is there is nothing to distinguish between indexes that represent a block of performance counters versus individual performance counters. As such, this listing does not go in numerical order and instead groups performance counters into their respective blocks. System indexes appear to at least have been hardcoded.
