In this video, I’m walking through 20 Windows commands every help desk tech should know. These are the kinds of commands that can help you troubleshoot real issues faster, understand what’s happening on a Windows machine, and build the kind of practical command-line confidence you need in help desk, desktop support, and early sysadmin work.
If you’re trying to break into IT, get better at troubleshooting, or strengthen your Windows fundamentals, this video should give you practical commands you can actually start using.
Coursera is also a great place to build the bigger-picture IT fundamentals behind these commands — networking, operating systems, troubleshooting, system administration, and security basics.
