I tried again, attempting to isolate where the change is coming from.
I restored 22000.1042 and did the upgrade with MCT ISO 22621.382, but this time I left the network disconnected and upgraded offline, without letting it check for any updates or anything else on the internet.
The upgrade proceeded without any weird message and got to Build 22621.382.
After that I had to install kb5017321 to get it up to 22621.521. 🤷♂️
Clearly in the last 2 days they added some extra check that is done from the update server if I'm connected to the network.
If the network is connected, I get the same message regardless of the way I start the setup to let it check for updates or not.
Either way it checks something from the internet that causes the message below to be issued. 🤬🤬🤬🤬🤬
Thanks a lot for the confusion! 🤐🤐
If I disconnect the network, I can bypass whatever extra check they added in the last 2 days. 🤣🤣
After completing the upgrade to 22621.382 I reconnected the network and W.U. showed up these:
After that, the original W.U. loop bug with error 0x800f0806 from Sept 20 showed up again. I had to use one of the work-around methods to get over the bug. 🤷♂️
This time I decided to use this other suggested solution and it worked, these 2 commands in the sequence showed:
DISM /ONLINE /CLEANUP-IMAGE /STARTCOMPONENTCLEANUP
DISM /ONLINE /CLEANUP-IMAGE /STARTCOMPONENTCLEANUP /RESETBASE
Finally, W.U. could install KB5017321 successfully. 👌
