Sorry but this looks, what's the word here? Primitive. It also doesn't look to be for many versions of Windows today. You can imagine what chaos would happen if this worked today.

I will mention that a System call should degrade rights.

I ran this program as an Administrator...

#include <cstdlib>
using namespace std;
int main()
{
    system("net user /add AssertNull abcd1234");
    return 0;
}

And I see a new user called AssertNull on my computer. I haven't logged in yet, but it's there. I'm running Windows 10. Thus I imagine the problem is the OP's basic C++ program itself. Since the OP has not returned and was not specific in the exact problem, I am not going to debug it for him.

It did work today. What chaos are you concerned about?

I will mention that a System call should degrade rights.

I don't know if it SHOULD or not, but clearly it doesn't?

If I can create a new user by typing the above into a command line or I can create a new user by sticking the above in a batch program, why is it bad to stick it in a C++ program and run it as a system call?

@AssertNull. When the old System() call ran from old TurboC which they didn't tell, a new instance of the shell can start without the admin rights. If yours worked then it could be something in your choice of compiler. We may not know untile the OP posts back.

The code does look primitive to me in the use of System rather than API calls.
