Normally when you turn on your computer, under the Windows 2000, XP and Vista operating systems, a window appears in which you must choose with which user you are going to log in, and in this way load the configuration that each user has predefined. But do not think that this only produces a single login.
Logon Sessions is a simple tool that will allow you to know exactly how many sessions are active on your computer at any time. In addition, if you specify the -p option, it will show you the running processes of each of the open sessions. It works under the MS-DOS system, through the command: logonsessions [-p].
You can free download Logon Sessions 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
