I tried to follow the procedure on that article, but after I change the registry as suggested and restarted it reverted back to ReleasePreview.
It is almost like the setting is cached in some other place too.
We'll see if Johnny has better success.
I don't really need it for now because my 3 old legacy bios machines where already in Development channel and could do the updates without any problem. Even the old Dell Optiplex 380 updated fine to build 2200.51 from 21390.2025.
Still would be nice to know if there is a way to jump back in if anything happens.
Hi fg,
I only had to change the first section for registry, the second from article was already there. It is holding in Dev channel after several reboots. Device shows install date of 5/26/2021 but WU would not install. It would go through process, report Secure Boot issue. That is with the 2 lines already added in registry (BypassSecureBootCheck) after 1st fail.
Next up ISO install on this device. Strange have no issue with virtual machines. It upgraded from 21390 via WU and also clean installed via default ISO in another vm. The Surface Pro upgraded via WU from 21996.1. Had to join Insider and it offered all 3 channels.
Regards,
Hi Johnny,
I repeated the whole procedure, but this time I started with a clean install of Build 22000 from the installation media that I created from the ISO I made from Software Distribution Download folder right after W.U. Downloaded the update to my first machine.
After that I could switch to Development channel just following that article.
In this case it did not revert me back to R.P.
As you can see here after reboot I'm in the correct channel.
At this point I should be able to get the remaining W.U. updates and get up to 2200.51, the clean install just put me to 22000.1
as you can see here.

And it is working just fine, downloading the update to 22000.51


Done ! Up to 22000.51 and still in development channel 😊
