Then off to the races to download and install the 22H2 update released today. Started at 1402 performing the download, install and restart. All completed at 1404 ... and that is not a typo!

The only thing I could think of as to why the fast update, is that the download had occurred in previous days and only required to turn on a switch or two. That has got to be the fastest update ever experienced. I even went back into the Settings to confirm that there were no other updates, there weren't any. And the Update History info was valid.
