I'm getting 3 updates -- the regular cumulative update, malicious software removal tool, and a .NET cumulative update. The .NET update is not always appearing at the same time as the other 2, only showing up after the 1st restart, and may or may not be named as .NET.
Microsoft added a feature to their Edge browser to enable it to start faster. Today there's an Edge update, to 89.0.774.48 . Restarting Edge after that update I lost the display -- it was as if the monitor went to sleep, but would not wake up, so had to do a power off. Turning Startup boost [settings -> System] off before updating Edge seems to have cured or at least avoided that problem on a 2nd copy of Win10, though that's Not enough evidence to say Startup boost is definitely at fault.
