Working on the Hosts file can be a pain as it is hidden in various ways to make it difficult to get to.
To avoid all the hassle of finding and unprotecting the Hosts file I use a neat little utility called HostsToggle.
It allows you to check, edit, or temporarily disable the Hosts file without any expert knowledge.
It automatically locates the Hosts file and also unlocks and relocks the file each time you edit the file.
HostsToggle adds a red button to the system tray, from which you can enable/disable, check and edit your Hosts file.
