You use Windows — now understand it

You click icons every day, but under that friendly desktop is a serious operating system. This course takes you from casual user to power user: someone who opens a black terminal window on purpose and knows exactly what they're doing. It's the on-ramp before the advanced Windows for Hackers course, so we keep it calm and beginner-friendly.

A light mental model of Windows

At the core is the NT kernel — the part that talks to your hardware and enforces every rule about who can do what.
Settings for the whole system and every app live in the registry, a giant central database (you'll rarely touch it as a beginner — just know it exists).
Background programs called services keep running even when no window is open (updates, networking, printing).
Your storage is split into drives with letters — the main one is C:\, and paths use backslashes like C:\Users\You.

How each lesson works

There are no videos here. You learn by reading the theory, seeing the tools and the method, then doing it yourself on your own Windows PC. Stuck? Every challenge has a Show solution with the exact steps.

⚙️ Method

Theory — understand why it works.
Tools + method — what to open and the approach.
Challenge — try it yourself.
Show solution — step-by-step, only if you're stuck.

🎯 Challenge: Open the Start menu, type cmd, and press Enter. In the black window that appears, type ver and then hostname. Note what each one tells you about your machine.

Show solution

ver → prints your Windows version number — useful to know exactly which build you're on.
hostname → prints your computer's name on the network.
That black window is the Command Prompt. You just ran your first two commands — welcome to the power-user side.
