The final tab in Task Manager is the Users tab. In most situations, this tab won’t be very helpful to you, since the only user connected to your system will be you. However, if your system is set up as a VPN server or you’re using the Remote Assistance feature, this tab will display other users connected to your PC. By right clicking on a user in this list you can send them a message, connect to their session, disconnect them, log them off, and more.
Once you take the time to start using Task Manager regularly, it’s really hard not to use it. Not only does it give you excellent high-level details about what’s going on with you system, but it also provides a great deal of control over system resources, especially the ability to free them up. Once other hidden tool that is particularly useful is the ability to launch new tasks from Task Manager. The File menu gives you access to New Task (Run) command, which is much more useful than you might think. If you or an application ever accidentally kills your main explorer.exe process, the quickest way to get your desktop back is by hitting Ctrl+Alt+Delete, choosing this option, typing explorer.exe, and clicking OK. No reboot required.
