Master Essential Windows CMD Commands for Network and System Management

ipconfig

Function: Query the local machine's IP address.

Usage: Open a CMD window and type ipconfig.

msg

Function: Send a text message to another computer.

Usage: Know the target IP, then run msg /server:TARGET_IP * Your message here.

net user

Function: View and manage local user accounts.

Usage: Similar to ipconfig, it supports many sub‑commands. For example, net user username password /add creates a new user named username with password password.

net share

Function: List shared resources.

Usage: Run net share to display all shares, and net share ShareName /delete to remove a specific share.

nslookup

Function: Check the IP address of a website.

Usage: In the command prompt, type nslookup domain.com to retrieve its DNS records.

netsh wlan show profile

Function: Reveal Wi‑Fi configuration details, including passwords.

Usage: Execute netsh wlan show profile SSID key=clear (replace SSID with the network name) while connected to the network; Windows returns the profile information and the clear‑text password.

telnet

Function: Access a remote text‑based service; famously used to watch a Star Wars ASCII animation.

Usage: Type telnet towel.blinkenlights.nl and wait for the animation to start.

Pipe operator (|)

Function: Redirect the output of a command to another destination.

Usage: Append | followed by the target, e.g., dir | clip copies the directory listing to the clipboard, or ipconfig | output.txt saves the result to a file.

Logical AND operator (&&)

Function: Chain multiple commands so they execute sequentially only if the preceding command succeeds.

Usage: Place && between commands, for example ipconfig && ping 8.8.8.8, which runs the ping only after ipconfig completes successfully.
