Then, there's also the UI that is just... awful. Touch-oriented white-on-white macro bullshit for people with poor vision. It's a smaller gripe and easier to fix, but still.
Windows 10 really feels like something that Microsoft decided to stuff down everyone's throat just because they were in position to do so. It clearly shows that MS treats users as a cattle, basically. You can moo all you want, but that won't change a thing. If you don't think it's true, look at LTSB (or what it's called now) - that Windows 10 edition for people who are really paying. Can't piss them off, so - no ads, no Windows Store, no Cortana or any other crap just gushing out mainstream Windows releases. So it is perfectly possible for MS to release reasonable OS editions _and_ they readily recognize their bundled junk for what it is, it just they don't give a fuck of what unwashed grey masses want.
So, yeah, Windows 10 is the worst piece of software. Not because it's lacking in the tech department, but because of a fundamentally rotten and disrespectful attitude towards their users on Microsoft's part.
Especially perhaps if you were lured in to the free upgrade route from Windows 7, which means your hardware is decent but not the latest and greatest. Fortunately, I made image backups when I upgraded.
Normally we'd think of updates as the correct thing to do to maintain your PC. So I find it insulting that it is the updates that are breaking the system.
