An unexpected error occurred during the update process

Hi expert friends,
When I try to update windows in my computer, it throws me an error message. This error stopped me from going further in update process. It’s an individual PC not connected with network. No clue in the error message, anyone else has faced this kind of error message before? I don’t understand what is going on exactly. Very badly I need help. Thanks.
