  3. The system will ask “Do you want to allow this app to make changes to your device?” question.
  4. Click “Yes” button.
  5. Select File and then Open in Notepad.
  6. Circumnavigate to C:\Windows\System32\drivers\etc\hostsor simply press the “Enter” key after pasting the path into the address box at the top.
  7. Select “All files” using the “File name:” drop down menu, if you do not find the host file in the /etc directory.
  8. Add an IP address and hostname at the end of the host file.
  9. Click on the “Save” button and then close the file.
