Hi,
It is a pleasure to answer your question.
For the problem you are experiencing, first I suggest you browse this article to fix the Windows update issue:
Fix Windows Update issues
These steps should help resolve all Windows Update errors and other issues.
If the above steps did not help you, the following is a situation I have encountered, because the system font file tahomabd.ttf or related process interferes with the automatic update process, resulting in error 0x80070020. Related discussion:

If the above method does not help you, please let me know.
