Hi ,
These are the hardcoded DNS domain names that will resolve to their proper IP addresses regardless of what you put into the HOSTS file:
The reason Microsoft added it is to prevent malicious software and/or people that wanted to use their computer’s HOSTS file to override some name resolution from doing so. This means that even if you edited the HOSTS file and added records to it that changed the name resolution to Microsoft’s update servers, proper name resolution would still work and the operating system would be able to go to the Microsoft update servers, allowing the OS to update itself, regardless of the changes to the HOSTS file.
For more details, you can refer to the following article:
