I've written an ATL Performance DLL using Visual Studio 2005.
AFAIK, when a performance DLL is linked to a NT service, the
Performance registry key is located under the service key
(HKLM\SYSTEM\Current Control Set\Services\XXXXX\Performance).
XXXXX is used in the macro BEGIN_PERF_MAP found in the CPerfMon
derived class.
The problem is that in this specific case, unregistering a
performance DLL recursively delete the service key ! Is there a way
to change this behavior without rewriting all the unregsiter code.

I'm not really familiar with ATL's performance counter support. If the
registration code for those is based on .RGS files the way it is for COM
DLLs, then just add NoRemove keyword in front of Servces key in your RGS

necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
