Hi again Max.
In researching this I found this thread which has the only known solution that worked for many others: https://answers.microsoft.com/en-us/windows/for...
I realize it pertains to Version 1709 but try it anyway and if those are not still the correct .cab files we will find them.
Also if it's Task Scheduler that's driving these repeated attempts then you can type that in Start Search, right click to Run As Admin, click on Library in left column, scroll through to find the scheduled task and disable it.
If you don't yet have Version 1803 this may be why it's happening because it was solved in the later version. To manually Upgrade to the latest version install Media Creation Tool from this link http://windows.microsoft.com/en-us/windows-10/m..., open the tool, choose Upgrade this PC now.
I hope this helps.
