Need to figure out how to edit the Hosts file in Windows 7? For the most part, it’s pretty much the same as Windows XP and Vista, but with a few extra hiccups!
Just if case you don’t know, the Hosts file is where you can manually enter a hostname and an IP address pair, thereby bypassing the DNS server. This can be pretty useful in certain situation, especially for anyone in IT.
The path to the Hosts file in Windows 7 is the same as usual:

%systemroot%\system32\drivers\etc\

where %systemroot% is usually c:\windows unless you installed Windows on a different partition. By default, you cannot see these hidden folders since they are system folders.


Need to run "Notepad" as administrator to update the host file.
