All the MCT downloads are available here - Download Windows 11
The release notes are available here - Available today: The Windows 11 2022 Update
However, BE AWARE that the MCT & .ISO install Build(22621.382)
You need to install KB5017321 Cumulative Update for Windows 11 v 22H2 Build(22621.521) via W.U. to bring your installation up to date.
There is an old bug showing up when I try to upgrade with the official ISO, it upgrades fine to 22621.382, but the subsequent W.U. check for updates goes into a loop trying to download and install KB5017321 over and over. Logs error 0x800f0806 on update history.
There is no way out of the loop.
I tried on 3 different boxes and got the same problem.
The 1st box I upgraded directly with W.U. completed fine to 22621.521, but not the two upgraded using the MS MCT ISO. 🤬🤬🤬
I remember this bug with some of the old Dev Builds, now it is back with 22621.
What a mess! 🤷♂️
I think I'll restore back to 22000.978 and stay there till MS fixes this bug.
