# Windows Command Prompt (CMD) Commands Guide

## Introduction

Welcome! This guide collects commonly used (and some advanced) native Windows Command Prompt (cmd.exe) commands to help with file management, networking, diagnostics, automation, and system administration.

Focus: Classic CMD commands (not full PowerShell coverage). Where a command is deprecated or superseded, a note is included. Many commands require an elevated (Administrator) prompt.

## How to Read & Use This Guide

Tips:
- Use `command /?` for built‑in help (often includes switches not listed here).
- Prefix with `runas /user:Administrator` or open an elevated terminal when access is denied.
- Combine commands with `&&` (only run next if success) or `||` (run next if failure).
- Use quotes around paths containing spaces: `"C:\Program Files\App"`.

Legend:
- (Admin) means the command typically needs elevation.
- (Deprecated) indicates the command is legacy; prefer the noted alternative.
