Microsloth Windows
     
         /mi:'kroh-sloth" win"dohz/ (Or
        "Windoze", /win'dohz/) A derogatory term for {Microsoft
        Windows} which is so limited by bug-for-bug compatibility with
        {mess-dos} that it is agonisingly slow on anything less than a
        fast {486}.  Also called just "Windoze", with the implication
        that you can fall asleep waiting for it to do anything; the
        latter term is extremely common on {Usenet}.
     
        Compare {X}, {sun-stools}.
