Problem 1: KB5001330 Update Installation Issues

The first and the most likely problem to experience with this update is Windows 10 KB5001330 failed to install issue. Users are extremely annoyed with this problem as they are unable to install this latest update on their Windows 10 computer.

Not just this, but while attempting to update OS, Windows 10 update KB5001330 fails to install along with several errors such as 0x800f081f, 0x800f0922, and 0x800f0984. Here is an example of just one of the user who is asking for help to fix this error:

As part of the current ‘Patch Tuesday’ windows updates, there is a Cumulative update KB5001330. This update fails to install on my desktop PC with the error code 0x800f0984. My installation of Windows10 is insider build 19043.899, Version 21H1. The update fails to install either from the Windows Update service or if downloaded and installed from the Windows Update Catalogue. I notice that the information in the Windows Update Catalogue states that the update is for two other Build numbers but doesn’t mention Build 19043.899. Could this be the reason for the install failure? If so then why does the update appear in Windows Update? I have successfully applied this update to two laptops, one running the same insider build as my desktop and the other one running a ‘normal’ non-insider build.
