Windows spontaneously and unexpectedly restarts overnight

Hello,

What would cause Windows 10 to spontaneously restart on its own overnight?

It seems like similar restart occurred a while back (weeks-to-months) as well, but when getting to my computer this morning, it was clear that it had restarted overnight.

I looked for some indication of a Windows update having been installed but could not determine where to look to see a history.

Is it likely a Windows issue and if so, where can a setting be changed so that I can modify it to restart only when I want?

Also, if it is not a Windows issue, is there some kind of log kept by Windows that will tell me what/why/when it occurred or some other way to diagnose it?

Thanks

windows updates is the first thing that comes to mind considering the changes microsoft made to its behavior

need to determine cause first before looking at how to fix
if it is windows updates, you can change the working hours so that it only reboots in a certain time frame

Also, if it is not a Windows issue, is there some kind of log kept by Windows that will tell me what/why/when it occurred or some other way to diagnose it?

look at event logs...start with that

This could be a Windows Issue, but it can also be indicative of some manner of hardware failure. If you're not finding evidence of a Windows Update, it's possible you're experience preventative restarts due to heat. These are particularly tricky to discover as they won't necessarily happen often if the hardware at fault is only just beginning to "go out". A somewhat reliable way to log this would be to run a Temperature Monitor on your machine that logs relevant heating data and compare event log shutdowns to temperature spikes in the monitor's log.
