Windows 10 is just fine until it reboots without permission (in the processing closing a dozen running applications and corrupting or discarding open files) to apply an unwanted update that breaks a driver that's been working for years. Then, said driver doesn't get fixed for six months, leaving you with expensive hardware reduced to a doorstop. Yes, all of the above happened to me.
Windows 10 is unpredictable, unreliable, and unsupported. Not my idea of great....but I've been stuck with it for over a year so it doesn't matter to me in the context of RM.
I have been on Windows 10 since day 1 and never once have I seen that behavior. My ITS department at work will force reboots but I have never experienced Windows 10 doing that on its own. In fact I have seen on many occasions that Windows 10 is requesting a reboot and give you the chance to choose reboot now or schedule a reboot. I would be very interested to see the system and application logs on any Windows system that are rebooting on their own. I am sure there is more at play then just a Windows update.
