Nvidia Control Panel shows auto-selects Integrated GPU despite definitions of the NvOptimusEnablemen

Executable of our application exports NvOptimusEnablement:

__declspec(dllexport) DWORD NvOptimusEnablement = 0x00000001;

However, Nvidia Control Panel auto-selects Integrated GPU. Interesting, that once application is run, actual GPU seems to be a discrete one. Which suggests a bug in the Control Panel.
