Why dll injection dont work on Windows 10?

:) Has Windows 10 adopted techniques against DLL injection? I am injecting into a user process like notepad but the dll is not started. I see that the thread is created by the return of createRemoteThread but does not open the selected dll (messageBox). I'm in windows 10 64Bit but I'm compiling both dll and injector in 32 bit. Thanks very much !! :) :)

Here the code: Dll File

*****************************************************************

#include <Windows.h>



BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{

if (ul_reason_for_call == DLL_PROCESS_ATTACH)
        MessageBox(0, L"Hello From testlib!", L"Hello", MB_ICONINFORMATION); 

    return TRUE;
}
