Windows OS is made up of a million components including apps, processes, drivers, and so much more than meets the eye. Even when your system is idle, thousands of processes are running in the background that you may not even realize. Aren’t there a few times when your system performs seemingly slow, even when you’re not working on any active apps?
As soon as our device’s performance slows down, the first thing we do is to check the Windows Task Manager. Right? Windows Task Manager neatly lists down all the apps and processes that are running in the background along with their CPU/disk usage mentioning how many system resources they are utilizing at the moment. And once we track down the app or process (aka culprit) that has been consuming maximum CPU usage, we instantly terminate that process. So, have you ever come across the Rundll32 Windows host process in the Task Manager window?
