I checked out the link, and now confess to being confused about versions, updates etc. I thought that I had a tenuous grip in the 1903, 1909, 2004 business, but the H2 stuff adds to my confusion.
For the time being I have reduced my status to that of a whimpering infant, and followed the path of allowing Microsoft to do what's best for me.
That is, I have checked my updates (again) and as of about ten minutes before this post, I was up-to-date.
All of this started with a view to using Task Scheduler for tasks besides System Restore Point creation, and things are spiraling out of my control.
The latest stopping-point was the missing checkbox, and to that end I have a vague idea that I might restore from an earlier ISO, just to see if that checkbox appears. That is, I might have tweaked the system in a way that has corrupted (shameful thought) Microsoft Windows.
Although that thought causes me to tremble.
