BigFix Microsoft Patch Rollback Task Wizard not work

[Boice]

I created and executed a rollback task. After the task was completed and the client was restarted, the client update was still not uninstalled.
After studying the script, I found that in the Window10 1909 version I used, the registry key name did not match, and not all the KB provided in the analysis could be uninstalled.
Will someone correct the above problems?

1.Completed tasks

2.undone

3.The key name used in the script

4.Correct key name

I’m not certain whether a Feature Update (upgrade to Win10 build 1909) can be rolled back at all, much less rolled back via the Wizard…if you try to manually roll back that patch does that even work?

Thank for your reply.
As you know, not all Feature Update can be rolled back. Unless to check uninstall button showing at installed Updates. It is another question for patch management , when the roll back analyze work on , you can check all the KB in the computer interface. But there are no judge for it ,you don’t know if it can be uninstall.
By the way , even I choose one show uninstall button at installed Updates , rolled back Wizard also failed.

uninstall button showing at installed Updates
KB in the computer interface.
