Do spawned threads automatically run as the identity of the user?

Question

ie

static void Main(string[] args)
{
    var thread = new Thread(WhoAmI);
    thread.Start();
}

static void WhoAmI()
{ 
    //can i access network resources as the user who ran Main?
}

Answer 1

Yes, they do.

// So yes, you can.

Answer 2

Threads don't have identity, processes do. So yes.

Edit: As Michael points out, it is possible for a thread's execution context to impersonate a user other than the one that owns the current process. But this will not happen unless you do it explicitly.

Answer 3

Yes. In fact, it would take some effort to make the Thread able to access resources as a different user.
