Windows only: Free application ProcessQuickLink adds small icons to the left of every running process in the Windows Task Manager that—when clicked—tell you what that process does. The app looks up its information from ProcessLibrary.com, which provides a description of the process and recommendations for whether or not you should feel comfortable disabling it. When your computer seems slow and bogged down with running processes you can’t make heads or tails of, ProcessQuickLink’s seamless integration with Task Manager seems like the perfect way to hunt down and eliminate your unnecessary processes. For a full snapshot of all your running processes and their priorities, check out previously mentioned ProcessScanner. ProcessQuickLinks is freeware, Windows only.
