Imported the WU-Setup log.xml into Event Viewer. KB4023057 does not show up anywhere. Nor does it appear anywhere in Control Panel/Programs and Features (by any name). Could just be one of those never to be understood Windows things.
It's strange that your 2/2 installation of it is not shown in the Event viewer, Custom view WU - System log incl Apps - see post #5
[It's not shown in the Event viewer, Custom view WU-Setup log that you've just referred to.]
The Progs & features list shows it by its other names - see post #5
[The Progs & features, View installed updates list does not. That's what you have just posted.]
You can probably already appreciate why I've ended up using multiple Custom views to help me investigate updates.
All the best,
Denis
