useful CMD commands — Windows Command Prompt and PowerShell can help you inspect your system and complete routine tasks. Commands may behave differently depending on Windows version and permissions. Read each command before running it, and avoid pasting commands from unknown sources—especially those that download or execute files.
Basic navigation and files
In Command Prompt, use dir to list files, cd to change folders, mkdir to create a folder, copy to copy files and ipconfig to view network configuration. Use help to discover built-in command help.
Network checks
ipconfig /all displays detailed adapter information. ping example.com tests basic reachability. tracert example.com shows the route toward a host. nslookup example.com queries DNS. Network policies and firewalls can affect results.
System information
systeminfo displays Windows and hardware details. hostname prints the device name. In PowerShell, Get-ComputerInfo returns broader system information, while Get-Process lists running processes.
PowerShell file and process commands
Use Get-ChildItem to list items, Get-Location to show the current path, Get-Service to list services and Get-Help to read command help. Use Get-Command to find available commands.
Disk and Windows checks
chkdsk checks a file system; repair options may require administrator rights and a restart. sfc /scannow checks protected system files. DISM /Online /Cleanup-Image /CheckHealth checks the component store status. Read Microsoft's current guidance before repair operations.
Use commands responsibly
Open an elevated terminal only when a task requires administrator rights. Understand what a command changes before running it. Do not use destructive commands on a system you do not own or administer. Back up important files before disk or system repairs.
Frequently asked questions
Are CMD and PowerShell the same?
No. Command Prompt is an older command-line shell, while PowerShell is a more capable shell and scripting environment.
Do commands require administrator access?
Some read-only commands do not. System repair, service changes and protected operations may require elevation.
Can a command damage Windows?
Yes, especially commands that delete files, modify partitions, services or system settings. Verify commands before running them.
