How many Windows sessions are in use when connecting to a user session via RDP

Question

================= 
Hello guys,
could you help me please? Below videos show a Windows 10 machine with user connected locally via VMware console. Then another user connects to the same machine via RDP and tries to take over the console session. The first video shows it via SYSTEM account, the second video via standard user account.
Questions of the day:

1. How many active sessions do you see in usage at any given point of time?
2. Do you ever see two sessions active at the same time?
3. Do you consider this a Windows 10 license violation?
   Cheers

Answer 1

1."How many active sessions do you see in usage at any given point of time?"
there will be only one active session on windows10 by default.
2."Do you ever see two sessions active at the same time?"
there will be only one active session on windows10 by default.but if we install third party sotware(like RDP Wrapper)on win10 ,it will increase active session number but it will violate EULA.
3. Do you consider this a Windows 10 license violation?
no.becasue from your video ,there are only one active session(userA or userB) being used.
I can reproduce this by design behavior on my work environment.like picture .
we can use query user command and quer session to check if there is only one active session.
