Hello Lilliana,
Welcome to the Microsoft Community! We're thrilled to have you here.
According to your description, I understand that you are having issue "How to Enable/Disable copilot in word ". Let me help you with that.
I am pleased to inform you that, thanks to proactive feedback from users like yourself, the development team has taken this issue seriously. In the latest version of Word (version 2506), the development team has added a button that allows you to disable all Copilot prompts in Word with a single click. To do this, please open the Word application, go to File > Options > Copilot, and uncheck the "Enable Copilot" option.
Currently, this feature to disable Copilot is only available in Word; it has not yet been added to Excel or PowerPoint, as the development team has received the most feedback from Word users. If you have any thoughts or suggestions regarding the use of Office applications, please feel free to share them with the development team at any time by using the File > Feedback button within the application. The development team is committed to listening to user feedback to improve Office.
I hope this information helps you solve your problem. If it's useful for your problem, mark it as helpful or useless so it can be useful to others.
Thank you for your patience and understanding.
Best wishes,
