There has been a degree of speculation that Microsoft are simply not interested in Windows desktops anymore. Their money comes from services; Azure, 365 etc. plus, of course, virtual windows-based desktops, for which they can charge a recurring fee rather than a one-off Windows licence.
And it’s not as if this, somewhat cavalier, attitude to updates quality is a new thing, how long ago was it since a Windows update decided to flush users’ data down the toilet?
Now, if, if, Microsoft are pivoting away from being focussed on making money through the Windows OS and stand alone Office installations, then the first thing you start to do is reduce the resources allocated to supporting them and checking that updates don’t do anything stupid, yes?
