Default values in the properties

[Lokoko]

Whenever I create a new file in Excel, Word or Powerpoint, the general
properties are filled out automatically with default values. How can I
prevent this from happening ? where do I need to change these default
values?

Thank you in advance

What general properties are you referring to?
