Hi All,
I understand you are stuck in a trouble caused by this issue which is caused as target system version (without 2020 9B / 10B package) is lower than existing system version (with 2020 9B / 10B package) . Here is a workaround which could help us get out of it. Please try on your side.
First, we need to rollback to previous OS. Then re-launch the in-place upgrade to a target OS with dynamic updates enabled OR in-place upgrade to an OS image that contains 2020 9B / 10B package or later.
Admins may be successful initiating an OS rollback remotely within the 10 days. The default value is 10 days, we also could configure it through DISM command line (run as admin) as below.
DISM /Online /Set-OSUninstallWindow /Value:<days>
Tip: If value passes anything <2 or >60, the default value of 10 will be set.
Then roll back with the command line DISM /Online /Initiate-OSUninstall [/NoRestart|/Quiet]
For more information about this command tool, please refer to DOCS: DISM operating system uninstall command-line options
Important: OEMs shouldn't use this setting in imaging or manufacturing scenarios. This setting is for IT administrators.
Windows gives a user the ability to uninstall and roll back to a previous version of Windows.
For adding update package into ISO image, we could use DISM tool with add-package parameter.
More details about it, please refer to: To add packages to an offline image by using DISM
Or we could configure image through SCCM.
At last, Thanks for all your patience and continued use for Microsoft products.
Bests,
Joy
