- Open the hosts file on your Desktop with Notepad or any other text editor.
- Make the necessary changes and move the hosts file back to C:\Windows\System32\drivers\etc directory.
Solution 3 – Make sure hosts isn’t set to Read-only
By default, hosts file is set to Read-only which means that you can open it, but you cannot make any changes to it. In order to fix this issue, you need to turn off Read-only mode for hosts file by doing the following:
- Go to C:\Windows\System32\drivers\etc.
- Locate the hosts file, right click it and choose Properties from the menu.

- Click Apply and OK to save changes.
Now you should be able to make the necessary changes to hosts file. After you’re finished, it might be a good idea to set hosts file back to Read-only mode again.
Sometimes, all your documents are read-only, including your hosts file. If you want to change them properly, you can find more info about that in this quick guide.
Solution 4 – Change the security settings for hosts
Sometimes in order to access certain files and folders, you need appropriate privileges, and the same goes for hosts file.
If you’re getting “Access denied” while trying to change hosts file, you might not have full control over the file, but you can easily change that by following these steps:
- Navigate to C:\Windows\System32\drivers\etc.
- Locate hosts file, right click it and choose Properties.
- Navigate to the Security tab and click Edit button.
- You should see the list of users and groups on your PC that have access to hosts file. If your user name or group is on the list, click it and make sure that it has Permissions set to Full control. If your user name isn’t on the list, click the Add button.
- Enter the user name or the group name in the Enter the object names to select field and click Check Names and OK.
- New user or group will be added to the list. Now you need to select the newly added group or user and check the Full control option below.
- Click Apply and OK to save changes.
Solution 5 – Use the hidden administrator account
Most system files are protected, therefore you need an administrator account in order to make changes to them. Since hosts is one of the system files, it requires an administrator account in order to edit it.
If you don’t use an administrator account, you can enable hidden administrator account and use it to make the changes to hosts file. To enable hidden administrator account, do the following:
- Press Windows Key + X and choose Command Prompt (Admin).
- When Command Prompt opens, enter net user administrator /active:yes and press Enter. This will activate the hidden administrator account.
- After you have activated the administrator account, you can switch to it, and try editing the hosts file.
After you made the changes to hosts file, you can come back to your original account, start Command Prompt as administrator again and enter net user administrator /active:no to disable the hidden administrator account.
Hosts file is a system file, so it’s protected, and usually it’s not advised that you edit it, but if you decide to do so, it’s always good to know how to reset hosts file to default in Windows 10 in case anything goes wrong.
