Windows 11 CO-Release Build 22000.51 is out to Dev Channel

Yes that is what I am saying - downloading was very inconsistent. Rebooting way before I finally did might have fixed the hiccup sooner but I just waited.

After reboot it should just continue on from where it was at the point when you rebooted

Over the years I have had insider downloads the the progression meter still says 0% through the whole download and all of a sudden it is ready to install so I don't go by what it says for sure

Hi,

Tried again last night - but when I checked no downloading was happening according to my internet connection. I left it for over half an hour but no dice. Don't know what the problem is with my machine, but windows 11 just wont install.

Anybody got any other ideas of how to fix this?

There is several obvious flaws in this build, so likely Amanda and Brandon will announce an update very soon

Created an ISO from the first PC updated, which resulted in build version 22000.1.210604-1628.

This was used to install on another non compatible PC, where I had to rename appraiserres.dll to be able to install.

All went well, until the system was to install the cumulative update KB5004564. It downloads and installs the update, but fails on reboot with error: Installation Failure: Windows failed to install the following update with error 0x800F0823

Any ideas?

Maybe you hit the problem with windows defender going from 1.341.xxx to 1.343.xxx.

Try updating defender directly and once you get over that 1st error the next W.U. should work.

I did the same procedure as yours yesterday and everything worked fine and got to 22000.51.

I just finished another update a few minutes ago on a Legacy BIOS MSI Laptop and I'm up all the way.

Or could be this:

Windows 10 DISM Servicing Stack Error 0x800f0823 - Microsoft Q&A

B.T.W. I have both 22000.1 and 22000.51

Thanks for the reply. Had just retried the update and it finally installed successfully. Will take note when updating the others to .51
