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

@Mark

You are way too impatient🤣🤣

Since you are having the same problems as I seen I am guessing you are also downloading to a hard drive which takes alot of hours to update and since Microsoft servers are likely overloaded with everybody trying to download the same thing it is worse at the moment. If you had a ssd it is way faster. You may have to leave your computer on downloading for a whole day the way things are right now. I think mine took something like 6-7 hours to download.

If you look in task manager under App history and at the top of the screen under options make sure that show history for all processes is checked and if you scroll down the list you should have a total MB downloaded that is highlighted with a way larger number under something like Host Process For Windows.

As long as this number continues to get larger if you are not downloading something else you are getting more of the download. This number should stay the same even after you reboot and continue to get larger as the download comes down

Good Luck

Edit

I tried downloading Windows 11 to a large partition on my computer that I haven't used for a while because it was so slow to update and the downloading pretty much just stalls out after the 8% glitch so maybe this is your problem.

I even tried the delete download folder trick and didn't help

The successful installations I did were on about 60GB partitions

I am also looking for the ISO for Win11 from the dev channel. It appears from several of the pages in Windows Insider that it should be available to download, but the drop down options are only for various Win 10 builds. https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso is the page I'm trying to get an ISO from currently.

Have you noticed that the bluetooth says "not connected" even though it is connected in the quick settings area

I have reported that in FBH

Update Windows 11plz

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

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