Runtime Broker is one of the essential background services present in Microsoft Windows. Its main feature is that it controls the rights of apps and keeps the system secure. It keeps track of how the apps you download from the Microsoft Store use your most private parts, such as your webcam, mic, or where you are. Runtime Broker only operates when necessary and mostly requires very few computer resources. Unfortunately, if a program does not function properly, it can lead to an increased CPU or memory load. Closing the offending apps or restarting your device normally is the way to fix the problem. In a nutshell, it serves as a security measure that safeguards your privacy and the overall safety of your system.
