Windows7 will not let me edit the hosts file and save it
It’s a built-in safety feature. There is an easy workaround. ClickStart ->All Programs -> Accessories. Right-clickNotepad, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or clickAllow or Yes.
Open the Hosts file (from the notepad you just opened) , make your changes, and then click File ->Save.
