NtCreateToken example for creating elevated token without user password

You can find samples from Google, like
SeCreateTokenPrivilege.cpp
But I get STATUS_PRIVILEGE_NOT_HELD as Admin on Windows 10
(cannot enable SE_CREATE_TOKEN_NAME privilege)

Well, it can be done. Here's a standard user - Bozo with an elevated Administrator command prompt running.

#include <sddl.h>

#include <vector>
