When installing Microsoft Office on your new computer, you have the option to install it for all users or just for your account. If you choose to install for all users, it will be accessible to anyone who uses that computer. This can be beneficial if multiple people in your household will be using Office. However, if you are the only user or prefer to keep it limited to your account, you can choose not to install for all users.
Since you have upgraded to a family membership, you should be able to install Office on both your old and new computers without any issues. Just ensure that you are signed in with the correct Microsoft account associated with your subscription during the installation process.
