Documented way - use performance registry.
Be careful - doing this incorrectly can trigger loading ALL of the perfmon
DLLs in the system (for things like IIS & MSSQLServer, for instance).
This takes ~10 seconds. MSVC5 has this bug in its process list window.
Undocumented way - use NtQuerySystemInformation syscall. This is how
Resurce Kit utilities work.
See www.osr.com or www.sysinternals.com for details on the syscall (AFAIK
one of them described it).

The PSAPI DLL exports a set of functions, which could be used to
obtain the processes, Process IDs and the path names in the system.
U do this in the following way,
1. Call EnumProcesses
2. Call EnumProcessesModules
3. GetModuleBaseName, GetModuleFileNameEx
If u have MSJ subscription, or if u'va got MSDN sub. then look into "Under
the Hood" article in Aug '96 by Matt Pietrik. That's a good one that
explains u how to do this.
Regards,
Chaitanya
