Re: [Shameless plug]Wikipedia article
I don't have a Wikipedia account and I'm too lazy to register for one. But that page says that there's only one window manager available for Windows. This isn't true - there are several derivatives of Blackbox that run on Windows.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
