Please run DISM again with Process Monitor running, there has to be a clue somewhere why it fails?!
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
square (CTRL +E) 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 the
LogFile.PML and upload it to
WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free and provide the link.
