windows - Microsoft Office Tools- permanently remove author name

I am having some trouble with Microsoft Office tools, I want to permanently remove the author name from all future created documents.

Word, Excel, etc, keep pulling my computer login username (Lets say JCTechie) and adding it to the author field. Even when I go into Options>Personalize>username and created a blank or false name, it doesn't take effect. It always shows as (JCTechie) when right clicking the .doc or .xlxs file- details- author. Is there a way to stop automatically adding the author or to change it to a blank space/ no entry? I know I can inspect the document and remove all data, but it's tedious to do for every document I create, especially if I were to forget to do it.

I'm using Office 2013 locally, not signed in to a Microsoft account.
