1. Restoring the hosts file in the Windows operating system
The hosts file in the Windows operating system is located in the driversetc folder under the system folder. The specific path is C:WindowsSystem32driversetc. Follow the steps below to recover accidentally deleted hosts file.

1. Start Windows Explorer and navigate to the C:WindowsSystem32driversetc folder.

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

Note: The above content is the basic content in the default hosts file. If you have customized the hosts file before, you need to copy and paste the backup contents line by line into the newly created hosts file to ensure that the previously performed domain name mapping still takes effect.

5. Save and close the hosts file.
