Editing the hosts file on Windows 10 using Command Prompt might sound like a techy task, but it’s actually pretty straightforward. You’ll be opening a special file on your computer and editing it to control how your computer looks up website addresses. This can help with things like blocking certain websites or testing your web projects before they go live. In just a few steps, you’ll be able to make the changes you need.
Step-by-Step Guide to Edit Hosts File Windows 10 CMD
In the following steps, you’ll learn how to use Command Prompt to open and edit the hosts file on Windows 10. These steps will guide you through navigating the system, opening the file with administrative access, making the necessary changes, and saving your edits securely.
Step 1: Open Command Prompt as Administrator
Type "cmd" in the Windows search bar, right-click Command Prompt, and choose "Run as administrator."
It’s important to run Command Prompt as an administrator, because you’ll need special permissions to edit system files like the hosts file. If you skip this step, you might run into "Access Denied" errors.
Step 2: Navigate to the Hosts File Directory
In Command Prompt, type cd C:WindowsSystem32driversetc and press Enter.
This command will change your current directory to where the hosts file is located. Think of it as telling your computer, "Hey, we’re going to be working over here."
Step 3: Open the Hosts File with Notepad
Type notepad hosts and press Enter.
This command will open the hosts file in Notepad, allowing you to edit it. Notepad is a simple text editor, making it perfect for this task.
Step 4: Make Your Edits
Add the IP address and domain name you wish to map, formatted like 127.0.0.1 example.com.
Now you can type in the changes you want. For example, if you want to block a website, you can map it to 127.0.0.1, which is the loopback address for your own computer.
Step 5: Save the File
Click "File" in Notepad, then "Save."
Saving the file is the final step. Make sure you don’t use "Save As" which might change the file format or location.
After completing these steps, your computer will follow the new rules you set in the hosts file. If you mapped a domain to a specific IP address, your computer will follow that instruction next time you try to access the domain.
