Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Anshul Pawar,
Thank you for reaching out to the Microsoft community. We are delighted to offer our assistance.
Generally, the pre-installed versions do not need to be activated as they are not Microsoft 365 apps, please check with acer for details on whether the product activation code comes with the laptop or requires you to purchase a separate Microsoft 365 license.
Thank you for your understanding and cooperation! Have a great day.
Sincerely,
Sean | Microsoft Community Moderator
