If you often keep many programs running on your PC simultaneously and forget to close some down, which clogs your system, you'll welcome this freebie. JustCloseSomeTasks gives you an exceptional amount of control over closing tasks you no longer need to run.
Press a hotkey, and the program pops up, showing you all of the tasks currently running on your PC. The Windows Task Manager does that as well, but JustCloseSomeTasks goes well beyond what the Task Manager can do. In addition to closing tasks, it lets you close tasks just for this session or for future sessions as well. Better yet, it indicates which tasks haven't been used for a period of time, and you can tell the program to close those automatically.
Most people most likely won't need this program. But if you wish you could automatically close tasks that you haven't used in a while, JustCloseSomeTasks is a great bet.
