Answer 1

[DllImport("user32")]
public static extern long SetWindowPos(long hwnd, long hWndInsertAfter, long X, long y, long cx, long cy, long wFlagslong);
[DllImport("user32")]
public static extern long ExitWindowsEx(long uFlags, long dwReserved);
[DllImport("shell32")]
public static extern long ShellAbout(long uFlags, long dwReserved);

public void DoExitWin(int flg)
{
bool ok;
TokPriv1Luid tp;
IntPtr hproc = GetCurrentProcess();
IntPtr htok = IntPtr.Zero;
ok = OpenProcessToken(hproc, TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, ref htok);
tp.Count = 1;
tp.Luid = 0;
tp.Attr = SE_PRIVILEGE_ENABLED;
ok = LookupPrivilegeValue(null, SE_SHUTDOWN_NAME, ref tp.Luid);
ok = AdjustTokenPrivileges(htok, false, ref tp, 0, IntPtr.Zero, IntPtr.Zero);
ok = ExitWindowsEx(flg, 0);
}
