@JOE TAM
Thanks for your posting Q&A.
We suggest to post one issue into one thread. But there are four questions in your post. To avoid misunderstanding, it is recommended to resolve the issue one by one. Or you could also open a new post and we could discuss the other issues on the new thread.

Here is the explanation of the error code:
0x80242017 WU_E_UH_NEW_SERVICING_STACK_REQUIRED The OS servicing stack must be updated before this update is downloaded or installed.
For Windows Server Update Services (WSUS) deployment:
