Windows Update Troubleshooter:

I am a computer technician. I am seeing multiple computers failing to install KB4522355.

In all cases I am seeing:

Performance slows considerably

All cases have been Win10 Home 1903, Issue not seen in Win10 Pro

This is how I fix:

MSCONFIG: Disable non-Microsoft services, UNTICK startup items

Reboot

MSCONFIG: Enable normal startup, DO NOT REBOOT

This is so next reboot will be normal mode

WINDOWS UPDATE : KB4522355 Is optional, select to download it. Updates now download & install correctly

REBOOT

Performance returns to normal

WINDOWS UPDATE : check for further updates

I had the same problem, this is how I solved it:

- I checked out the windows update log at <WindowsHome>\Logs\CBS\CBS.log

- The log had errors: "STATUS_OBJECT_NAME_NOT_FOUND", "ERROR_FILE_NOT_FOUND"

- I saw the problem begining with this: "Exec: Warning - Manifest doesn't exist for:"

- Then in the line below it was talking about a resource localized: "Component Identity: Microsoft-Windows-MFPlat.Resources, Culture=fr-CA"

- I have multiple languages in my PC, English / French but the problem is specific with french.

- I login with every user and deleted the "French - Canada" languages (From "Settings -> Time & Languages -> Language")

- I let only English (US). Then I went to "Administrative language Settings" in that tab (right corner) and with "Copy Settings" option I let only English for Display language, Input Language and Format.

- Reboot

- Try again and everything works without issues.

Conclusion: In my case it was due to the multiple languages configuration. The update seems to be incomplete or not build properly.
