Mirosoft ?
Not a term I recall using and jolly close gatesworld.
I have on occasion been required to utilise the "GatesWerld" OS.
OK so I would like to live in Linux but I have been doing Macintosh for fifteen years now.
I gave up Old Holborn, more or less, but the a 'friend' gave me this stunning ligther that looks and feels like a miniature pipe wrench !
