I've got a system service that needs to access a user's registry value. 
I've written a function to impersonate the user and then access the registry 
(HKEY_CURRENT_USER), but it always get back a false value (see code below). 
Am I not impersonating the user correctly?  Is there a better way to access 
this Registry value from my service?

    HANDLE hToken = NULL;
    HANDLE hDupToken = NULL;
    bool boolRet;

    try
    {
        try
        {
            DWORD dwSessionId = WTSGetActiveConsoleSessionId(); //Get the 
user's session ID
            if (dwSessionId == 0xFFFFFFFF)
                return false;

            WTSQueryUserToken(dwSessionId, &hToken);    //Use the session ID 
to get info on their security token
            if (hToken == NULL)
                return false;

            //Get an impersonation of their token
            DuplicateToken(hToken, SecurityImpersonation, &hDupToken);
            if (hDupToken == NULL)
            {
                CloseHandle(hToken);
                return false;
            }

            //Impersonate the logged on user
            BOOL bRes = ImpersonateLoggedOnUser(hDupToken);
            if (bRes)
            {
                TRegistry *ptr_Reg = new TRegistry;

                try
                {
                    ptr_Reg->RootKey = HKEY_CURRENT_USER;
                    ptr_Reg->OpenKey(USERREG_KEYPATH, false);

                    boolRet = ptr_Reg->ReadBool(ACCESSREGVAL);
                } __finally {
              ptr_Reg->CloseKey();
                    delete ptr_Reg;
              }
            }
            else
                boolRet = false;
        } __finally {
            CloseHandle(hDupToken);
            CloseHandle(hToken);
            RevertToSelf();
            }
    } catch (Exception &exception) {
        Sysutils::ShowException(&exception, System::ExceptAddr());
        }
    return boolRet;

Thanks,
