I have try to use ExitWindowsEx( , ) and "rundll32 shell32,exitwindows", but it doesn' t work.

From what I've noticed, WinPE can only shutdown if you kill the shell or initiate a crash command. Does your build include reset.exe/shutdown.exe?

A dirty way is to call shutdown.exe or just run pskill and kill the whatever shell process you got

I managed to get WinPE to reboot by calling NtShutdownSystem, exported from NTDLL.DLL

something like this:

typedef enum _SHUTDOWN_ACTION

{

ShutdownNoReboot,

ShutdownReboot,

ShutdownPowerOff

} SHUTDOWN_ACTION;

typedef DWORD (WINAPI* lpNtShutdownSystem)(SHUTDOWN_ACTION Action);

HMODULE hNTDLL = LoadLibrary("NTDLL.DLL");

if (hNTDLL)

{

lpNtShutdownSystem NtShutdownSystem = (lpNtShutdownSystem)GetProcAddress(hNTDLL, "NtShutdownSystem");

if (NtShutdownSystem)

{

if (msg.wParam & EWX_SHUTDOWN)

NtShutdownSystem((msg.wParam & EWX_POWEROFF) ? ShutdownPowerOff : ShutdownNoReboot);

if (msg.wParam & EWX_REBOOT)

NtShutdownSystem(ShutdownReboot);

}

}

FreeLibrary(hNTDLL);
