One reason to use the Task Manager in Windows is to see if any of the apps running on your computer are misbehaving or using a disproportionate amount of resources. But what do you do when the misbehaving app is Task Manager itself?
After a recent Windows update, some users (including Windows Latest) noticed that closing the Task Manager window actually failed to close the app, leaving the executable running in memory. More worryingly, every time you open the Task Manager, a new process appears on top of the old one, which you can essentially repeat indefinitely (or until your PC collapses under the pressure).
Each instance of Task Manager takes up approximately 20 MB of system RAM and varies between 0 and 2 percent CPU usage. If you only have a handful of copies open, you're unlikely to notice much of a performance impact. But if you use Task Manager regularly or go a long time between restarts, opening two or three dozen copies of the process that all occasionally use a fraction of your CPU can add up, leading to a potentially significant impact on performance and battery life.
