Thank you Windows 10 for rebooting, without warning, to install an update when I was in the middle of working on something.
Looking at my screen, 20 minutes later, I see it is at one percent and that my PC will reboot several times.
You were explicitly told to not reboot because I was busy. I have work to do. Yes, even early on a Sunday morning.
You did it anyway.
This is why I am now checking out a Visual Studio project on a damned Linux box, hunting down where I was and recreating my edits.
Windows is next to useless for anything beyond gaming.
