The Internet connection must be working for Windows updates to be downloaded. When working offline and trying to update Windows manually, you may not notice the state of the internet connection. In this case, try to open websites on your browser to check your internet connection.
2) Do not temporarily let your antivirus scan the SoftwareDistribution & Catroot2 folders
Antivirus programs are known to report genuine programs and files as viruses or malware. If the files in the SoftwareDistribution and Catroot2 folders are identified as threats, the antivirus software will prevent Windows from updating.
