Just last night my box happily rebooted itself as it spontaneously updated itself despite all my wishes.
I hate it when that happens.
My Win10 VM at work periodically disappears from my RDP connection (disconnects me, logs me out, loads updates, and reboots) without my approval. Very annoying, since I sometimes have a fair amount of context on the desktop from day to day.
I've had to stop using Win10 for anything that might have to run overnight. Luckily the things I have to run overnight will also run on my Win7 VM. Other than the Win10 compatibility tests...
Most of what I do that's important, I now do on Linux. Windows is relegated to transient tasks that, if they die when I'm not looking, I don't lose significant context.
It's really a shame -- only 5 years ago I was using Windows as my primary desktop environment at work (had done so for the prior 8 years) and it was fine. That's just a fond but dimmer-every-year memory.
