Processes or Troubleshooting Courses?

I am interested in learning both statistics and basic computer processes for the purpose of easier navigation and troubleshooting in Windows 10, at least to start. For statistics, I’ve found a ton of content, but I don’t know what academic keyword to use for the processes content above, if there are any options available on this site. Can anyone direct me anywhere, or have any resources where I can find this info? Thanks in advance!
