My first post after exhausting all attempts to resolve my windows update error. After looking at the log file I assumed Avast was causing the problem. I uninstalled Avast and also ran CCleaner to remove any left over entries. The problem still persisted. I hope the attached files are the correct ones that are required :noidea:. Help to resolve this would be greatly appreciated. :thumbsup2: The CBS file was 10.5MB after zipping and couldn't upload.
