Key notes

  • This file is essential in mapping hostnames to IP addresses on the Windows 10 operating system.
  • Upgrading to a new version of Windows, malware infection, and incorrect edits are reasons to edit the file.

The hosts file is an essential component of your computer. If it has changed for some reason, don’t panic, you can quickly reset Windows 10 hosts file.

So, in this article, we’ll explore some common triggers of host file changes and show you how to set the default values for this file on the MS operating system.

What is a Windows hosts file?

The Windows hosts file is a text file in the Windows operating system that maps hostnames to IP addresses. It acts as a local DNS resolver and allows you to map domain names to IP addresses manually. 

This file is usually used to block or redirect network traffic and can be helpful in a variety of scenarios, such as:

  • Blocking ads – You can add entries to the hosts file that point to the IP address of ad servers, effectively blocking all ads from displaying in your browser.
  • Website testing – You can use the hosts file to test a website before it goes live by pointing the domain name to a specific IP address.
  • Redirecting traffic – You can redirect traffic from one domain name to another by pointing the domain name to a different IP address in the hosts file.

However, sometimes the hosts’ file can become corrupted or modified by malware, which can cause issues with network connectivity. 

In such cases, resetting to its default state can be helpful. Here are some common reasons why someone may want to reset this file:

  • Malware infection – Malware can modify the hosts file to redirect your web traffic to malicious sites or block access to legitimate sites. Resetting the hosts file can help to remove these malicious entries and restore normal network connectivity.
  • Incorrect manual edits – If you have manually edited the hosts file and made an error, this can cause issues with network connectivity. Resetting the file can help to remove any incorrect entries and restore proper functionality.
  • Upgrading to a new version of Windows – Upgrading to a new version of Windows can sometimes cause issues with the hosts file. Resetting the file can help resolve compatibility issues and restore normal network connectivity.
