(1) As soon as we start Windows, some applications are running in the background. Because they are running and consuming computer resources, rams, CPUs, etc., you have to give them away unnecessarily. So it is a good idea to turn off such applications without your knowledge.

Right click> disable any unwanted applications and close them.
