I try to load my driver with following code..

	bool rt = Privilege(L"SeLoadDriverPrivilege",true); // I got SeLoadDriverPrivilege privilege

	HINSTANCE hDll = LoadLibrary(_T("c:\\windows\\system32\\ntdll.dll"));
	*(FARPROC *)&NtLoadDriver = GetProcAddress(hDll, "NtLoadDriver");
	_LSA_UNICODE_STRING drv = toLsaUnicodeString(L"\\Registry\\Machine\\System\\CurrentControlSet\\Services\\\DemoDriver32");
	NTSTATUS ntStatus = NtLoadDriver(&drv); // --> returns 0xC0000033

Open in new window

Registry of "\\Registry\\Machine\\System\\CurrentControlSet\\Services\\\DemoDriver32" includes followings..
