Built-in commands can hide, encrypt and cloak your files.copy /b an image plus a zip folder into a new image to tuck the archive inside what looks like an ordinary photo; cipher /e on a folder encrypts every file so only your account can open them; attrib +h +s +r on a folder makes it vanish from view, and the same flags with minuses bring it back.
Windows stores every saved Wi-Fi password, readable in plain text.netsh wlan show profile lists every network the machine has joined; adding the network name and key=clear shows its password. Chuck runs a one-liner that dumps all of them, redirects it to a text file, and saves it as wifi.bat so it runs by name; he says the command is in the description, not read out.
Curl ships with modern Windows and does far more than downloads. Chuck uses it for weather (curl wttr.in/Dallas), unshortening a link by fetching headers and piping to findstr location, checking a site is up (curl -Is, which returned 200 OK), finding the public IP via checkip.amazonaws.com, drawing QR codes, dictionary lookups, latest-video and tweet lookups, and querying ChatGPT with a long command he leaves in the description.
Small tweaks make Command Prompt faster to live in. Set the shortcut to run as administrator by default; type cmd in Explorer's address bar to open a prompt there, or explorer . the other way; subst S: "path" mounts a folder as a drive (subst /d S: undoes it). F3 repeats the last line, F7 lists past commands, doskey /history prints them all, and color, prompt … $G and title restyle the window. The video is sponsored by ITProTV, now ITPro from ACI Learning.
Chuck's real advice is to leave Command Prompt for Terminal and PowerShell. Windows Terminal, built into Windows 11 and installable on Windows 10, adds tabs, drag-and-drop file paths and "open in terminal" from Explorer. He still uses Command Prompt out of career-long habit, but calls PowerShell more powerful and the thing to learn for anything deep.
