windows 10 2004 update confusion.. please help

I too wasn’t seeing the message yet no update. I expect the rollout isn’t being offered to all PCs at the same time.
I used the media creation tool. Beware if you have Malwarebytes installed though as it’s causing major slowdown of Windows after installing 2004, you either have to install MB Beta version or turn off ransomeware protection.
2004 fixes the high CPU usage.

I blogged about this very topic for Win10.Guru on June 3: If 2004 Upgrade Not Blocked, Does Phased Offer Still Hold? – Win10.Guru. The net-net is that MS is doing a "phased rollout" so that only a few machines get the offer at first, with more following in some kind of cadence thereafter. Of the 6 machines I have that were eligible for the upgrade, for example, only one of my PCs got an offer from Windows Update. I still have two machines I deliberately haven't upgraded (an ancient 2011/2012 Jetway mobile Ivy Bridge CPU rig, and a 2018 vintage Lenovo X1 Extreme with a 6-core Kaby Lake mobile CPU) and neither one has gotten the offer yet.
HTH,

Ha, ha @Cr00zng: an apt observation. I've never been able to figure out how MS manages the "trickle-out" when the phased release is underway. Throwing spaghetti on the wall is as good as an analogy as any. Thanks for the laugh.

Even more unfathomable for this release. At least for past rollouts MS have made statements like '...starting with newest machines tested by our partners...'.

But for 2004 of all my physical machines only two of the oldest (2011 & 2012 vintage) have been offered it (but not the oldest at 2009). My newest (Dell Latitude E7270) is on the OEM list for 'tested for 2004' but is yet to see it offered. Even for my VMs only one is offered it. Go figure....


Edit: after the cumulative update today to 18363.900 my 4th oldest machine, a Dell Latitude E4310, has now been offered the 2004 update.

Still seems pretty random to me, too, @Bree. I just gave up this afternoon and updated my X1 Extreme (8th Gen Intel CPU: Kaby Lake?). Went through without a hitch, and pretty fast, too using Update Assistant. Sigh.
