Hosts file location in Windows 7
It seems this folder has some strange hidden attribute on it. I have show hidden files and folders and show protected operating system files on, and I couldn't browse to it. However if you actually type it into the address bar you can get there!
(After doing this, I now /can/ browse to it, so I can't test other folder options settings to see what makes it show up.)
EDIT: For clarity, tested on Windows 7 Ultimate x64.

You might have the Windows Explorer Folder Options set to "Don't show hidden files, folders, or drives" which prevents you to see the hosts file.
To fix that and Show the hidden files do:
- Open Windows Explorer. click "Alt" button to bring up the File menu if you don't see it. Click on "Tools" and then "Folder Options..."
Click on the "View" tab and enable the radio button "Show hidden files, folders, and drives"
For a quick browse to the location do: Start-> Run->
%systemroot%\system32\drivers\etc\Run as Administrator your file editor in order to make changes to the hosts file
