In windows, the hosts file is used to resolve domain and IP address mapping, so when you use a domain name in a web browser or other client tool, windows will first find the domain’s related IP address in the hosts file, if found then use that IP to communicate with the server, if not found then it will query the domain’s IP from the DNS server configured.
The hosts file is located in C:\Windows\System32\drivers\etc in windows, the file location for each windows version is the same, but for windows 10, the edit method is not the same as windows 7 or earlier. You may find you can not save the file when you edit it.

- After investigating, I found the C:\Windows\System32\drivers\etc folder ( that contains the hosts file ) is read-only, so I attempt to change the etc folder’s read-only attribute.
- I right-click the C:\Windows\System32\drivers\etc folder, then click the Properties menu item in the popup menu list, it will display the etc Properties dialog window.
- But when I uncheck the Read-only checkbox in the Attributes section and click the OK button, it prompts the below error message also, the prompt dialog said access denied, I need administrator permission to change the read-only attribute.
