I have a dedicated BI machine. I have another machine that runs my home automation system (CQC), a DVR system (SageTV), and my IP phone system that runs on a virtual machine running Linux on this Windows machine. Both of those computers are "mission critical" in my house and both run flawlessly. I even have automatic updates turned ON because I haven't had issues and I want my machines to be as up to date as possible without my intervention. These machines run so reliably that I rarely RDP into the machines, so updating them manually would be a pain in the ass.
Now for the sake of complete transparency, my son had an issue with his custom built gaming system recently that caused the sound to stop working (the machine recognized his hardware, but failed to be able to use it). Personally I think it was a registry issue that might have been caused during an update. He did have to reinstall Windows 10 to get everything running again. He even bought a sound card during this process and the new hardware wouldn't work until he reinstalled Windows. However there is no telling what might have happened with that computer - He built it, he uses it, and I never look at it. The other 4 Windows 10 machines (not including the BI or automation computer) that are all used daily (two laptops and two desktops) haven't had any issues either. So out of the 7 Windows 10 machines we run in our house, only one has had an issue that I can remember - the sound driver issue that my son's gaming computer experienced recently. All 7 computers have automatic updates turned on.
Long story short, the days of blaming "Windows" for issues is long gone. Windows 10 is extremely reliable. That being said, it is a computer system and it is possible that something got corrupted - either in software or hardware. I'd start out by reinstalling Windows, but if the problem continues then that points to a hardware issue.
