Hi! Are you trying to change the default search engine for your pc or inside the Google Chrome app? if you are only using Google Chrome, Microsoft process to change it wont fit your needs as this is not a Microsoft software, you need to contact Google support.

But if what you are trying is to change the default browser so you can use only Google Chrome app, please follow this steps:
