2018-07 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4345421) – Error 0xca00a000”
This kind of Windows Update error pops up when Windows has missed installing one of the cumulative updates needed or when there is some problem with the driver that won’t let the installation of the updates push through. There are also instances when the system files are modified with incorrect permission that may result in the Windows update error 0xca00a000. Thus, you need to fix the trusted installer permission as well as resolve the issue with the driver. To do these things, you need to follow the options laid out below.
The Windows Module Installer is a built-in service in the Windows operating system that could help you resolve the Windows update error 0xca00a000. You need to make sure that this service is Started and that its Startup type is set to Automatic – you can do this via Services Manager or by executing the command given below in an elevated Command Prompt.
SC config trustedinstaller start=auto
As mentioned, the error might be because Windows missed installing a particular update which is why you are not able to proceed with the current update. So to resolve the issue, you need to install the update that wasn’t installed by downloading it from the Microsoft Update Catalog website. You also have to make sure that you didn’t turn off the Windows update or have it delayed.
The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.
net stop wuauserv
net stop bits
net start wuauserv
net start bits
Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.
You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

Error CausesComing in October for insiders and in November for all in the update, Microsoft has prepared a series of updates which they call an "additional set of experiences"
These updates are looked upon by Panos Panay, a vice executive president at Microsoft & chief product officer for Windows and devices as sort of makeup tests. They will consist of new additions with the biggest one being a tabbed version of File Explorer.

File Explorer received a UI makeover in the last update but the tabbed interface was missing which was expected by many users so it will come in following the next update.
The rest of the features that we will receive are an updated Photos application, Suggested Actions in the Windows Shell, Overflow menu for the taskbar, and improved Nearby Share.
The tabbed File Explorer interface is essentially File Explorer’s version of Sets, the tabbed window interface that Microsoft tested out several years ago. In testing, the tabbed interface proved handy for moving and copying files, and we’d expect the same once the feature formally goes live. The difference between Sets and the tabbed File Explorer interface is Sets allowed for multiple applications to be clustered together via tabs.
Photos app will include a “new photos-managing experience that brings a gorgeous gallery, simplifying browsing, finding, management and consumption of your collection of photos.” It will allow “easy backup to OneDrive” and a “delightful Memories experience.”
As for other features, nothing specifically was said except giving just some tips on what will they bring, it is obvious that File Explorer and the photos app were the main focus for MS in this upcoming update.
