Good evening,
After attempting to install the required KBs, please check the following log: C:\Windows\Logs\CBS\cbs.log. There you will be able to determine possible errors when performing updates, provided that you have checked the correct status of the equipment through:
1. Available disk space.
2. Correct status of Windows Update components.
3. Correct system status.
I look forward to your response.
Best regards, mate,

They mostly seem to say failed to internally open package with error 0x800f0805. When the install is attempted and it does fail, it fails within 5 to 10 seconds, but works on a retry. The error returned by the failed attempt is 0x8007139F but the log has been showing 0x800f0805.
