Hosts file editing: save problem

My Hosts file was lost so I downloaded a new one. This I edited to block two sites that had intruded and given trouble. I saved initially to desktop and then tried to paste and save it in to C:\windows\.......\etc , but failed to do so as error as per att, appeared,

I am a sole user/ administrator, and also have opened run Notepad as administrator to no avail.

What am I doing wrong?

Open an Elevated Command prompt and do the following:

cd \windows\system32\drivers\etc
attrib -h -s -r hosts

Copy the new hosts file to this directory

attrib +r +h +s hosts

exit

That should do it.

This one changes the current directory (the one you are in) to \windows\system32\drivers\etc. That's where the hosts file is located.

cd \windows\system32\drivers\etc

This one clears the Hidden (h), System (s) and Read Only (r) attributes, making the file visible and changeable.

attrib -h -s -r hosts

This one turn on the Hidden (h), System (s) and Read Only (r) attributes again to protect the hosts file from being easily modified.

attrib +r +h +s hosts
