And then Windows decides you've had enough time to reboot. And you have to click "Ask me again for reboot in 4 hours", because 4 hours is the maximum time the system will allow. And repeat this every 4 hours.

In Windows 10 it's even worse, you have to define off-hours when you're not using the PC, and in those hours the device will reboot itself if it feels like it. Don't worry, the applications you had open will be restarted, surely no data can be lost.

Edit: Windows 10 even has the configuration panel "Restart Options," which tells you "We'll show a reminder when we're going to restart. If you want to see more notifications about restarting, turn this on".

I've also had lots of trouble with failing updates.

Hey at least Windows 10 learned to reopen Explorer windows.

Nothing else though, but Explorer windows it sometimes manages to remember.

Not every time.

But sometimes.
