InternetSetOption() expects an HINTERNET handle as the first input
parameter.  You are not providing one.  You need to call InternetOpen()
first.  Specifying NULL means that you are trying to change the default
values, but those values are stored in the HKEY_CURRENT_USER key of the
Registry, which a service does not have access to by default.  You have to
impersonate a user login in order to change a particular user's Registry
settings from a service.   Look at LogonUser(), ImpersonateLoggedOnUser(),
and RevertToSelf().

Asside from that, please also provide the actual return values from both
InternetSetOption() and GetLastError().
