KB5006738 Windows 10 2004 19041.1320, 20H2 19042.1320, 21H1 19043.1320 Win Update

You must not be running the released version if on 21H2. This is a release version KB.

I got 21H2 1288 through WU KB5006670, wouldn't that be a release version?

Notice that the title of this thread has no mention of 21H2. I'm not sure what channel you are on, but it's not the release channel.

If you look at the top of post #1 Brink has links for the 21H2 Enablement package, you can go to 21H2 while staying on the release channel.

The KB5003791 Enablement Package allows you to go from 2004, 20H2, or 21H1 to 19044 (v21H2).

I'm confused. What channels are there, I'm not on insider, just been doing the WU and did the 21H2 enablement Brink posted.

Okay, them I'm definitely confused as I've been reading that 21H2 isn't going to be released until November.

Several 21H2 users in the thread apparently got the WU for 1320 ...

That's true. But although the Enablement Package is intended for Insiders, it's been available for some time and anyone can download it and use it. Probably you won't get everything that's due out in November. Some of that will be in the Feature Experience Pack, and there's no download for that. Windows Update only delivers it to Insiders.

I was able to get it through WU on my Release Preview (10) PC, and by manual install of the Catalog item on another (production) PC. No problems either way, and pretty quick through the update process, too.
