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.
