Oh please. You what I’m talking about.
It’s just that definition inconveniently keeps Windows at such a prohibitively high usage level, some people just merely decided to all of a sudden start to count the mobile OSs on phones so they push some narrative that they couldn’t do with desktop Linux and OSX.
I've *always* used that definition of OS--software that operates hardware.
That is why I have such a difficult time accepting that MS was allowed to get away with claiming that IE is part of the OS--it controls no hardware. Other applications as well should not be included. The OS should be merely a collection of drivers and firmware that controls access to the hardware.
Nothing more.
