Can’t save hosts file as admin?
Edit Your Windows 10 Host File as an Administrator – The HOSTS file is normally stored in a plain text file in the Windows System folder and can be modified for various use cases. One particular reason I edited the Host file in the past was to block certain websites when I imaged computers for a local high school.
This was probably one of the best and easiest ways I could ensure students didn’t load any unauthorized websites such as Facebook or YouTube. Editing your Windows Hosts file doesn’t have to feel like going down a rabbit hole. In Windows XP and earlier versions, the process was quite easy, add an exception to your antivirus, open it in Notepad, make your changes then save it.
In Windows 10, if you try to edit your hosts file, you’ll probably be able to open it just fine, but when you go to save it, you’ll get an error: Here’s how you can edit your hosts file without getting the “You don’t have permission to save in this location. Contact the administrator to obtain permission” error. Hit the start menu or press the Windows key and start typing Notepad, Right-click Notepad and choose Run as administrator, In Notepad, click File then Open In the File name field, paste the following path in: c:\Windows\System32\Drivers\etc\hosts
Now you’ll be able to edit and save changes to your HOSTS file.
To map a domain, add a line based on the examples in the HOSTS file. Start with the target IP address, then a space, then the domain name. If you want to block a website, redirect it to 127.0.0.1. Don’t put in the # if you want it to take effect. Also, remember that www.youtube.com is different than youtube.com. You may need to restart your computer for the new HOSTS file to take effect.

What is host file in PC?
What Is the Hosts File? – Definition from Techopedia The hosts file (“hosts.txt”) is a plain-text file that contains a list of host names and their corresponding IP addresses. It is essentially a database of domain names that is used by the operating system for identifying and locating a host in an IP network.
The forerunner of the Internet, the ARPANEt, did not have a distributed domain name database since the number of hosts then was very few. But as the popularity of the Internet increased, the idea of the hosts.txt file emerged because of the need to gather in a convenient place all the information about the different hosts in a network.
The format specification of the hosts file is described in RFC 952. The hosts file consists of one or more lines of text, where each line begins with the IP address followed by one or more host names separated by a space. The file may also contain comments, which begin with a hash sign (#); blank lines are ignored. : What Is the Hosts File? – Definition from Techopedia

The first section denotes the IP address where a request will be redirected to.The second section designates the location that we want to redirect a request from. The third section specifies a comment for the entry. Each entry is usually separated by a space or a tab.
