Marcycn, I’ve also used Microsoft Windows since late 80’s and beginning with Win 2.0 onwards, in those days I used it for a retail business and personal business use. And yes, I am a heavy user and have been for many decades and have learned how to and what not to do. Of course Microsoft had allot of problems in the evolution of Windows, its all part of the course but and until Windows 10 (and as far as I’m concerned) Microsoft has streamlined and has virtually devised an operating system that is very efficient and rarely goes wrong. They did have some problems, I admit (which I didn’t experienced at all with any updates and/or version updates) with v1903 May edition update which affected a very minute percentage of users like 0.00025% with e.g. brightness control on Intel GPUs, Audio does not work with Dolby Atmos headphones and home theatre, Folder in user profile empty, AMD RAID driver incompatibility, Upgrade error with connected USB devices and SD memory cards and Windows Sandbox ends with error “0x80070002” which was mentioned within many German forums, that happens when you cater for over 2 billion users.
In saying all this and as I’ve said before, Windows is like any other device, it has to be maintained, serviced and streamlined, both software and hardware wise and if users persist in using and installing all sorts of incompatible software and/or hardware and don’t clean their disks and updates out then problems will happen, with their operating system e.g. you have to do a "Disk cleaning" and the "Cleaning of system files" (after an update) also and what I recommend is for every user to back “Their Operating System” up with a reputable backup software.
