Change hostname windows

What you need to do is as following:

Open a terminal (hotkey is + + ).

Next, use any editor you favor to edit the following files (I use vi because I like it, but you can use anything else, such as gedit):

There you will see your current hostname, just change it to whatever you like the new machine name to be, save the file and quit.

Next, you will also need to edit /etc/hosts file, as following:

Locate the entry in the file that contains your current hostname and change it to the new hostname.

You can do this by typing:

Hit and you're done!

is your username. To change this, you should follow this answe
