Windows is much more than a graphical user interface. For those of us old enough to remember, we started our PC journey with MS-DOS and then Microsoft Windows. The command prompt was where we worked and we had to learn a few tricks to get the job done. Fast forward to today and we have complex graphical user interfaces that work extremely well, but sometimes the command prompt is just quicker.
In this how to, we have collected a number of common GUI tasks, and shown how the command prompt can be used to get the same job done. These commands will work with Windows 7,8,10 and 11.
Accessing the Command Prompt
1. Click on Start and search for cmd, click on Run as Administrator. With administrator powers you can do some damage, so double check what you are typing before you press the Enter key.
Clearing the Command Prompt
The command prompt can sometimes become cluttered, but we can soon fix that by clearing the screen with the cls command. Type the command and press Enter to gain valuable space in your command prompt.
clsGet Your Network Connection Details
We can easily get our network connection details via the Network and Internet section of Settings, but what if you need them in the command prompt? The ipconfig command provides us with our IPv4 and IPv6 addresses, DNS details and other basic networking information.
1. In the command prompt, type ipconfig and press Enter. This produces a basic overview of the network connections currently in use.
2. In the same prompt type ipconfig /all and press Enter. Using ipconfig with the /all switch shows a detailed breakdown of all the active network interfaces. These include our Bluetooth adapter and a virtual Ethernet adapter for our Virtualbox VMs.
Filtering Output With Findstr
Commands can generate a lot of output. So how can we filter out the noise and target the data that we need? Using the findstr command we can pass strings to search for in the output of a command.
Here is an example using the ipconfig /all command, piping the output via “|” to become the input of findstr, where we specify the search string in quotes. In this example we are searching for the Host Name of our machine.
ipconfig /all | findstr “Host Name”The findstr command can be used with many different commands, and using extra pipes we can direct the output to other tools / applications.
Checking Your Connection
Part of testing a network is checking that we can connect to another machine and with ping we can check our internal and external connections.
To check an internal connection, we will need to know the IP address of a device on the network. For that you will need to scan for devices on your network. Once we have the IP address we can use ping to check the connection.
ping 192.168.0.8
To check an external connection, we can use ping with an external IP address. Our go to IP address is one of Google’s DNS servers.
ping 8.8.8.8
IP Address Release and Renewal
Sometimes we need to release or renew the IP address of an adapter and this can be easily done via the prompt.
1. Use ipconfig /release to release all active connections. This will release all connections, Ethernet, Wi-Fi and Bluetooth.
2. Use ipconfig /release *Eth* to close all connections matching the “Eth”. This will close all Ethernet connections, but keep others open.
3. Use ipconfig /renew to renew all IPv4 connections. This will force all of the adapters using IPv4 to renew their IP addresses.
4. Use ipconfig /renew6 to renew all ipv6 connections.
Managing Tasks from the Command Prompt
The Windows Task Manager is the place to manage running tasks on your system, but we can also manage tasks directly from the command prompt with tasklist and taskkill.
1. List all of the running tasks by entering the command and pressing Enter. This will produce a list of applications, memory usage and a Process ID (PID).
tasklist
2. Use findstr to filter the tasks. In our example we are looking for “Inkscape”.
tasklist | findstr “inkscape”
3. Use taskkill to kill the session using its PID. In our example Inkscape’s PID is 1544.
taskkill /PID 1544
File Associations
We take it for granted that when we click on a file, it opens in the correct application. While we can edit the default application for a file type via the GUI, we can also do this via the command prompt. The assoc command is how we list and add a file association.
1. List the current files and their associated applications using assoc, press Enter to run.
assoc
2. Search for specific file associations using findstr and a string to search for. In our example let's search for the application associated with CSV files.
assoc | findstr csv
3. Associate CSV files to a text file, opened by Notepad. This is safer than opening the file directly in Microsoft Excel, where we can check the file before importing into Excel.
assoc .csv=txtfile
4. Repeat the search using assoc. You will now see that .csv files are linked to text files.
assoc | findstr csv
Saving to the Clipboard
Saving the output of a command to the clipboard can be a laborious task. Highlight the text, right click, copy and then paste into the document. But what if we could save the output on the fly? Using clip we can pipe the output of a command to the clipboard, from where we can paste it into a document.
1. Run the assoc command and pipe the output to the clipboard. The output of the command is redirected to the clipboard.
assoc | clip
2. Open a text editor and paste the contents of the clipboard.
Detailed System Information
If you need to know everything about your system then the systeminfo command is for you. This command will output information such as
- Memory
- CPU
- Hotfixes
- Network
- BIOS
Run the command from the command prompt. The output can be piped to clip for easy reading in a text editor.
systeminfoAutomatically Reboot into the BIOS
If you want to make changes – switching your boot order, for example – using your computer’s UEFI setup program, then you either need to know the right key to hit to enter your BIOS. Or you can use this command to do it all for you.
shutdown /r /fw /f /t 0The basic shutdown command can take a number of switches.
/r to reboot
/fw to boot the BIOS
/f to force applications to close
/t 0 to reboot now, with 0 referring to zero seconds.
Microsoft allows Windows 11 to be installed on older, unsupported hardware but specifically nixes official support — minimum requirements for full compatibility remain unchanged
Windows 11 for Arm can run natively on specific Android smartphones — the test device heats up very fast, and battery life substantially decreases
