How to Shut Down the System The following example uses the ExitWindowsEx function to shut down the system. Shutting down flushes file buffers to disk and brings the system to a condition in which it is safe to turn off the computer. The application must first enable the SE_SHUTDOWN_NAME privilege. For more information, see Privileges.BOOL MySystemShutdown() { HANDLE hToken; TOKEN_PRIVILEGES tkp;
// Get a token for this process.
if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) return( FALSE );
