    Microsoft 365 is usually linked to the Microsoft account used for the purchase, so a product key is often not needed to install it on a new computer.

    1. Sign in to the Microsoft account, Services & subscriptions page with the Microsoft account associated with the Microsoft 365 purchase.
    2. Find the Microsoft 365 subscription and select the install option.
    3. Follow the prompts to download and install the apps on the new computer.
    4. When an Office app asks for activation, sign in with that same Microsoft account instead of entering a product key.

    If Microsoft 365 was bought as a new, unused product key card, redeem it at www.microsoft365.com/setup.

    If the new PC shows a Let’s get started screen with options to try, buy, or activate Microsoft 365, that usually means only a trial version is preinstalled. In that case, sign in with the account that already has the subscription, buy Microsoft 365, or redeem a new product key.
