A troll whose disruptive posts typically proclaim that Microsoft
Windows is utterly superior to other operating systems (typically Linux), and that users of other operating systems like Linux are fanatics, lunatics, zealots, communists, anti-Americans, or hippies.
Wintrolls are most commonly found on the USENET newsgroup
comp.os.linux.advocacy, where for years their mantra has been that Linux is "not ready for the desktop" user market segment, and that less than 1% of desktop users run Linux.
They are also found on
urbandictionary.com, where they have been posting "definitions" of Linux that say only that it's "not ready for the desktop."
"Wintroll" is always capitalized.
