Hi there,
My first suggestion would be to try getting the updates manually and installing them.
Just type your KB number here and download the update
https://www.catalog.update.microsoft.com/Home.aspx
Next, you can try running the SFC & DISM commands to get this sorted.
In the search box on the taskbar, type Command Prompt, and right-click or press and hold Command Prompt (Desktop app) from the list of results. Select Run as administrator, and then select Yes.
Type DISM.exe /Online /Cleanup-image /Restorehealth (note the space before each "/"), and then press Enter. (Note: This step may take a few minutes to start and up to 30 minutes to complete.)
After you see a message that says "The operation completed successfully," type sfc /scannow (note the space between "sfc" and "/") and press Enter.
After you see a message that says, "Verification 100% complete," type exit.
