1475990 2021-03-31 09:11:00 Tonight I have downloaded update KB5000842 for Win 10 20 H2 (64) -seemingly no problems.
This is the second Cum update for 20H2 .
It is described as Cum update Preview for Win 20H2.

Why does the word Preview appear in the update title?
To me the use of the word Preview suggests intended only for Developers/Advanced Testers.
If so why should it appear in Windows Updates -Optional updates.?
I should have thought if Preview was as I mentioned above -it would only be available to those registered for the Windows Insider feature.

Comments please
Neil

1475991 2021-03-31 18:26:00 That Question has been asked a Lot, an answer on the Insider forums:


Previews are (non-security) bug fixes release on the 3rd/4th week of every month (so-called C/D releases). If you don't install it, those bug fixes will be lumped together in next month's patch Tuesday security fixes. When the Actual security update comes out there may be an updated or changed version of a bug fix or / and performance improvements. That's one reason its located under the "Optional updates".

Really not an highly accurate wording of what they actually are. But doesn't matter what they are called someone would always get confused and read them differently :)
