ExitWindowsEx can be used to shutdown the system. but he calling process must have the SE_SHUTDOWN_NAME privilege. See the following example from the SDK documentation:

The following example enables the SE_SHUTDOWN_NAME privilege and then shuts down the system.
 
HANDLE hToken;
TOKEN_PRIVILEGES tkp;
 
/* Get a token for this process. */
 
if (!OpenProcessToken(GetCurrentProcess(),
        TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
    error("OpenProcessToken");
 
/* Get the LUID for the shutdown privilege. */
 
LookupPrivilegeValue(NULL, TEXT("SE_SHUTDOWN_NAME"),
        &tkp.Privileges[0].Luid);
 
tkp.PrivilegeCount = 1;  /* one privilege to set    */
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
 
/* Get the shutdown privilege for this process. */
 
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,
        (PTOKEN_PRIVILEGES)NULL, 0);
 
/* Cannot test the return value of AdjustTokenPrivileges. */
 
if (GetLastError() != ERROR_SUCCESS)
    error("AdjustTokenPrivileges");
 
/* Shut down the system and force all applications to close. */
 
if (!ExitWindowsEx(EWX_SHUTDOWN | EWX_FORCE, 0))
    error("ExitWindowsEx");
