KB4559004 CU Win 10 v1903 build 18362.997 and v1909 build 18363.997 Win Update

Pray tell what is the preview? Prelude to 2004 ?

TIA

Just installed KB 4559004. Went smoothly, computer seems fine.
(Did make fresh MR backup, right before accepting the Update).

/e Just checked... still not offered May 2004 Feature Update.

Uhm, where is this cupdate anyway? All I see in Windows Update is KB4562900 for .NET framework 3.5 & 4.8. I know it's optional, but it's not even found nor listed to me which seems out of place..?

Not sure if its release preview ring, or if it is because I have the upgrade to 2004 option available to me.
But it wasn't showing up for me either. I finally just manually installed it from the MSU links in first post.

peace

Huh? I don't understand. Release preview for 1909? Is that still ongoing now that 2004 is out? All these rings makes my head spin. Not that I will click on it anyway, just curious to where it's hiding.

Whoops, I just read in small text here "Cumulative Update Preview".. So the update is being tested, and that's why I don't see it I guess?

Right, it is a preview CU for 1909, probably be released next (2nd Tuesday in Aug) patch.
And of course, there are still patches for 1909 even though 2004 is out, will be for more than a yr.

Right. I got confused because I've always seen optional updates (the ones that came after the 2nd tuesday) in Windows Update even though I'm not in a 'ring'. But I guess those were not in preview, but this one is? Makes sense I think, thanks.
