If you don’t want others on the LAN to access your computer, passwords are the first step. But what about hiding the PC completely so that it’s not even visible on the network?

To hide a computer from the network neighborhood you first must load up a command prompt (Start -> Run then type CMD and press enter). From there type ‘net config server /hidden:yes’ and then press the enter key. After that’s done the PC you’re working on should disappear from the browser list (note it can take up to 30 minutes). If you want the computer to show up again, simply replace the ‘yes’ with a ‘no’.
