Desktop/Laptops is now a 3-way split between MS, Apple and Google with chromebooks.
Mobile is a split between Apple and Google with MS out of it.
Cloud is Amazon out in front with MS in second place.
Office is the one area where MS could be considered to have a monopoly but even there I think cloud players are gaining ground and also (AFAIK) there's no advertising in paid for versions of MS Office.

Android dominates mobile OS usage, but iOS has equal profits if not greater than Android

I guess the perception of whether or not Microsoft effectively has a monopoly in the gaming PC market segment really centers around the games you play.
I guess we'll just have to agree to disagree. :)
Fortunately there's been a lot of great games coming out for Linux too recently, mostly thanks to cross-system frameworks like Unity, I assume. And that's great, but not really enough to threaten Windows' position in the PC game market.
In the US maybe (and I doubt even there).
In the rest of the world it's 90% windows machines.
In certain markets like schools, windows is down to 22% in the US and 65% Worldwide (https://9to5mac.com/2017/03/02/apple-ios-market-share-k-12-e...)
These don't really feel like monopoly numbers like we used to see around the 1995-2005 timeframe when Microsoft were at their most monopolistic.
Yes, speaking of desktop/laptop machines. It's Windows, OS X around 12 or so and the others closer to statistical noise.
Those even the 12% for OS X is in Western/Northern Europe mostly -- anywhere else it's closer to 95% Windows.
