Looking for registry setting

I am trying to find a registry setting that will for a check box to be
checked in my wireless settings.

The particular box I am looking for is under the "Wireless network
Connections Properties". Click the "Wireless Networks" tab, and the
check box in question is "Use Windows to configure my wireless network
settings".

I thought it might be HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
\Services\WZCSVC
But that seems to just affect the Wireless Zero Service.

Any suggresions would be greatly appriciated.

Thanks
Peter
