Hello, Carlos! This is a great introduction to some system utilities that are available with operating system applications. I also mentioned File Explorer and Task Manager in my post, which I think just shows how important a lot of these tools are. Also, I like that you mentioned Control Panel because it can take you to so many important settings and controls from security controls to hardware or even to the internet. It is great to have several different groups of options to work with. For anyone in the IT field or even anyone doing something related to it, all of the tools you mentioned are essential.
