Hi,

Turn off antivirus software before update.

We could try the following command line as administrator.

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

Then reset Windows Update with script: This script will completely reset the Windows Update client settings.

After that, we could try the following steps:

1. Create a new folder named as C:\temp\cab
2. Download update package from http://catalog.update.microsoft.com to C:\temp
3. Run command line below to exact .msu file for getting .cab file.
   expand -F:* C:\temp{.msu file name with extension} C:\temp\cab
4. Run DISM command line below to add .cab file.
   Dism /online /add-package /packagepath:c:\temp\cab{.cab file with extension}

If the issue persists, please check error codes recorded in the Event Viewer(Windows Logs\Applications, Setup, System).

Bests,
