Yes, but I don't see why it would matter.

The portion of the Tool Help library used in GnuPG only retrieves
information on processes, threads, modules, and heap allocations on the
system. AFAIK, this is quite similar as running 'ps aux' on Linux (but maybe
returns more details).

Tool Help _can_ be used to read the memory allocated to other processes
(using the Toolhelp32ReadProcessMemory API), but this isn't used in GnuPG
for obvious reasons - without a doubt it would require Administrator
privileges if run on Windows 2000, I haven't tried it.

Could you please clarify what do you mean by "questionable result"? And
there is hardly any performance penalty.
