After doing the steps above, please do the following:

Install Update with DISM

  1. Download this update and save to your desktop. The file name will be Windows10.0-KB4522355-x64_PSFX.cab.zip.
  2. Right-click on this file and select Extract All... Click the Extract button. You can close the folder window that opens
  3. Click on the Start button and in the search box, type Command Prompt
  4. When you see Command Prompt on the list, right-click on it and select Run as administrator. Go ahead and allow if you receive the UAC prompt.
  5. Copy and paste the following command into the command prompt window and press enter.

    dism /online /add-package /packagepath:%userprofile%\desktop\Windows10.0-KB4522355-x64_PSFX.cab
  6. You should receive the message:
    The operation completed successfully.
    Restart Windows to complete this operation. <---You may not get this line.
    Do you want to restart the computer now (Y/N)? <---You may not get this line.

Go ahead and do so if prompted. Let me know what errors if any come up. If you do get errors, please zip/attach your CBS.log

Note: If you get the message that no packages that require processing were found, use the following command instead:

dism /online /add-package /packagepath:%userprofile%\desktop\Windows10.0-KB4522355-x64_PSFX.cab\Windows10.0-KB4522355-x64_PSFX.cab

Let me know if successful and attach CBS.log if it fails.

Thank you.

Please note that my availability is going to be somewhat limited today which is why I am providing you with more steps than usual.
 
The DISM command failed with error 14003, saying that there are some assemblies missing. The attached CBS log contains both the log entries for the sfc /scannow and the DISM command.

Did SFC complete successfully now? What message did you get? The log was written over, so I don't know...

Step#1 - FRST Fix
NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system
1. Please download Farbar Recovery Scan Tool and save it to your Desktop.
Note: You need to run the 64-bit Version so please ensure you download that one.
2. Download the attached fixlist.txt and save it to the Desktop.
Note. It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work (in this case...the desktop).
3. Run FRST64 by Right-Clicking on the file and choosing Run as administrator.
4. Press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
5. When finished FRST64 will generate a log on the Desktop (Fixlog.txt). Please post the contents of it in your reply.

Yes, the SFC command did complete successfully. It said that there were no corruptions and everything's fine.

After applying the new fix, I tried to install the downloaded Windows10.0-KB4522355-x64_PSFX.cab file using dism. Hope that was correct, logs attached.
