Unlike Linux, majority of tasks are performed by User Interface in Windows. But still, there are certain tasks that can be done through Command Prompt (CMD)
To most, the command prompt is a somewhat frightening frill of the Windows operating system. The interface is black, bleak, and without much assistance. Compared to the rest of the Windows interface, it just seems empty. Despite its underwhelming first impression, the command prompt is one of the most powerful instruments in the Windows arsenal.
The command prompt is useful for everything from complex automation to network configuration. What it lacks in interface it more than makes up for in effectiveness. If you don’t know where to start with command prompt proficiency, what better place than to start here!
CMD Commands
While most seek the best and most useful commands immediately, it helps to gloss over what different parameters mean. Proficiency with your command prompt comes not only through having a lexicon of commands, but of understanding what each parameter means and how different parameters can be combined to achieve a desired effect as well.

Note: In order to have full access of the command prompt, you must run the prompt as an Administrator. Administrator privilege allows users to access commands otherwise inaccessible.
To activate Administrator mode, open your Start menu, type in cmd, right-click on the CMD program, and select Run as administrator. In Windows 10, you can also right-click the Start button and select Command Prompt (Admin).
Essential Command List
CMD commands number in the thousands, each one with its own action.
[command] /?
The above command provides users more information given particular commands. This tops the list, solely because it allows users the ability to figure out commands without having to rely on third party sources.Advertisement

chkdsk
Repairs file system errors, bad sectors, and recovers readable information. There are two methods of running the chkdsk command.
- chkdsk /F — Runs chkdsk and fixes file system errors.
- chkdsk /R — Fixes errors, locates bad sectors, and recovers information from those bad errors. A more comprehensive scan than /F.
ping, pathping, tracert
Ping and pathping (a more comprehensive form of ping) will echo or display data packets sent to and from a specific website. Pathping, along with tracert, will display the IP address of every router (or hop) on the way to your desired domain.

powercfg
By default, certain power configurations like Hibernation mode are off by default. Hibernation mode, as opposed to powering the PC off, will save the last state of your PC (programs, windows, etc.) and start up quicker. In order to enable or disable, use the following commands:
- powercfg /hibernate on — Turns on Hibernate mode, accessible through the default Windows power options.
- powercfg /hibernate off — Turns off Hibernate mode.
driverquery … > [File Name]
While most of us can’t make heads and tails of our PC drivers, there are times when driver issues will spring up. This may be as minor as a delay in performance, or as major as constant BSODs.
While the driverquery doesn’t present an immediate advantage, it does give an overview of the PC’s driver information in order to fully troubleshoot hardware and software issues.
- driverquery — Presents an assorted list of installed drivers.
- driverquery /FO TABLE, LIST or CSV — Presents your drivers as a Table, List, or excel spreadsheet.
If you add > [FileName.csv] to your original parameter — driverquery /FO CSV > driverquery.csv for example — your command prompt will take the information presented through driverquery and output it to an Excel sheet. The file will be directed to your Windows32 folder by default.
ipconfig /release, renew, flushdns
At times, network issues can occur through faulty IP addresses or corrupted DNS (Domain Name Server) files. To fix this, enter the following commands in order:
- ipconfig /release — Releases your IP address.
- ipconfig /renew — Replaces your previous IP address (and takes considerably longer to finish than the other two).
- ipconfig /flushdns — Erases the previously configured DNS listing, allowing websites that were previously unusable to load again.
It’s best only to do this when you’re having a network issue. More specifically, when you’re connected to the internet but certain websites won’t work.
Command Your Prompt!
The command prompt isn’t some strange beast made out to confuse you. It’s a simple feature, jam-packed with useful tools to control pretty much every aspect of your PC. We’ve only scratched the surface of what the command prompt has in store for you, so get to learning!
