I have run through the first 5 steps from the Windows Update Forum Posting Instructions without errors, but problem still persists.
Before that I tried to update several times and rebooted each time, but always get the same error.
Step#1 - Capture Process Monitor Trace
1. Download and run Process Monitor. Leave this running while you perform the next steps.
2. Try updating the system just like you have in the past.
3. Stop Process Monitor as soon as it fails. You can simply do this by clicking the magnifying glass on the toolbar as shown below.
4. Select the File menu...Save... and save the file to your desktop. This is likely the default location. The name (unless changed) will be LogFile.PML. This is fine.
5. Zip up and provide the link to the LogFile.PML file as well as your CBS.log Examples of services to upload to are Dropbox or OneDrive or SendSpace.
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.
Again failed with error:

Download the ISO file to your desktop.
Double-click on the ISO and then run the setup to try and upgrade your machine.
We want to get the ISO so that you don't have to keep downloading which can take hours.
Make sure you select keep personal files and apps when upgrading.
