[A question]

@Lena Loyd, Sometimes, due to unexplained crashes and/or extra rogue processes might result in a session not close even though the user logged off. The session will still active and applications/extra rogue processes might continue to run, but the user is no longer able to connect the session. 
When an administrator reset a session, it will forcibly terminate that session, applications/rogue processes in that session will be closed, resources used by applications/process will be released.
