Yes, it's easier to click on buttons, but a lot harder to explain to somebody.... click the button that looks like a blob, and on the bottom right find a button that has -- oh, wait.. are you using XP, 7, or 8? 8? Oh, sorry, not sure how it's done, but in Windows 7 it was here... you don't see it? Ah, it says this instead now... ok, yeah, click that, now look for this...

Much easier and less ambiguous (thus less likely to mess up) to say:

Open your command prompt and paste this exact command: <command>

I did tech support for a few years while in University, helping people with Windows 3.1, MacOS, etc, connect to the University's computers via a terminal server and later with SLIP and it was always easier to tell somebody an exact command to type than to have them search for buttons or checkboxes, etc... It was always easier to troubleshoot a modem by telling them hayes commands to type rather than trying to find obscure options in obscure menus in many different terminal emulators, such as Telix.
