Unable To Save Hosts File On Windows Vista Or Windows 7?

If’ you ever need to modify your Hosts file on either Windows 7 or Windows Vista, you’ll probably hit a warning that you need to be an Administrator to modify it?

Now this may seem odd as you’ve also probably already got Administrative rights on the PC?

This is a new safety measure originally introduced in Vista to stop rogue (spyware) applications from modifying hosts and redirecting traffic to other sites.

However, you can still modify the file:

Right Click on “Command Prompt” icon, and select “Run as Administrator”

cd \windows\system32\drivers\etc

notepad hosts

You should now be able to save the file without any problems.
