Blocking Access to Hosts on Windows 10
Blocking access to hosts on Windows 10 might sound complicated, but it’s actually quite straightforward. You just need to edit the hosts file, which controls how your computer interacts with the internet. By adding entries to this file, you can block specific websites. It’s like telling your computer to ignore certain addresses when it tries to connect to the internet.
How to Block Access to Hosts on Windows 10
The following steps will guide you through the process of blocking access to specific hosts on your Windows 10 computer. By the end, you’ll be able to prevent your computer from connecting to any website you want to block.
Step 1: Open Notepad as an Administrator
First, open Notepad with administrative privileges.
To do this, type "Notepad" in the search bar, right-click on it, and select "Run as administrator." This is essential because the hosts file is a system file, and you need admin rights to edit it.
Step 2: Locate and Open the Hosts File
Next, you’ll need to find the hosts file.
Navigate to this path: C:WindowsSystem32driversetchosts. In Notepad, go to File > Open and paste this path into the File name field. Make sure to change the file type to "All Files" to see the hosts file.
Step 3: Add the Desired Entries
Now, add the websites you want to block to the hosts file.
Simply add a new line at the end of the file and type 127.0.0.1 followed by the website’s address (e.g., 127.0.0.1 www.blockedwebsite.com). This tells your computer to redirect any attempt to reach that website to your own computer, effectively blocking it.
Step 4: Save the Hosts File
Once you’ve added the entries, save the hosts file.
Click on File > Save in Notepad. Ensure there are no extra file extensions added by accident, and confirm that the file is saved in its original location.
Step 5: Flush the DNS Cache
Finally, flush the DNS cache to apply the changes.
Open Command Prompt as an administrator and type ipconfig /flushdns, then press Enter. This clears your computer’s DNS cache and applies the changes you made to the hosts file.
After you complete these steps, your computer will no longer access the websites you’ve blocked. Instead, it will redirect attempts to visit those sites to your own machine, effectively blocking them.
Tips for Blocking Access to Hosts on Windows 10
- Always run Notepad as an administrator when editing the hosts file, or your changes won’t be saved.
- Be sure to add only one website per line to avoid any confusion.
- Remember to flush the DNS cache after making changes to ensure they take effect.
- Consider backing up the original hosts file before making any changes, just in case you need to revert.
- You can unblock websites later by simply removing the corresponding entries from the hosts file and saving it again.
