Reset hosts file

The Hosts file is used by the operating system to map human-friendly hostnames to numerical Internet Protocol (IP) addresses which identify and locate a host in an IP network. If you have done some configurations to HOSTS file on Windows, it might be a good idea to reset it. If the Hosts file is changed from default, resetting it can help resolve some connectivity issues.

The Hosts file in Windows 10/8/7 is located at the following location:

C:\Windows\System32\drivers\etc
Hosts file in Windows

Double check and make sure the website you're trying to visit isn't listed in there. If it is, remove it.

How to Reset Hosts File Back to Default?

Rename the Hosts file to hosts.bak . You may be required to take ownership of the file first.

In order to create a new default Hosts file. To do so, open a new Text file named "hosts" in the folder C:\Windows\System32\drivers\etc .

Copy-paste the following text into the notepad file :


windows host file

Click on the File menu and Save. Now you've successfully reset the HOSTS file back to default in Windows 10 . For Windows 8/7/Vista, the contents of the HOSTS file are different and you can copy them from Microsoft's website .

Reset Chrome Flags

Chrome has experimental features that normally are turned off by default. In some rare cases, an experimental feature may be enabled but that normally happens when the feature is fairly stable. You can change quite a few things and it's just as easy to change a flag back to its default value.
