I just bought Microsoft 365 Premium on-line on March 17, 2026. Microsoft sent ne an email with instructions to install without a Product Key. However, I have this information from the email.

I am really frustrated trying to install. I need help, please.

My system is Windows 11

Device: DESKTOP-UEBM5S9, HP Laptop 15-dy5xx

Subscription: Microsoft 365 Premium

Order Number: 6841810723

Thanks

Herald

    Follow these steps to install Microsoft 365 on the Windows 11 laptop after buying it online (no product key needed):

    1. Open a browser on the HP laptop and go to the Microsoft account Services & subscriptions page: https://account.microsoft.com/services
    2. Sign in with the same Microsoft account that was used to purchase Microsoft 365 Premium (the one that received the order confirmation email).
    3. In Services & subscriptions, locate the Microsoft 365 subscription that matches the recent purchase.
    4. Select Install next to that subscription.
    5. When prompted, confirm the device and follow the on‑screen instructions. A setup file (installer) will download.
    6. Run the downloaded installer and let it complete. The wizard installs Office apps in the background; keep the PC powered on and connected to the internet.
    7. After installation, open an app such as Word or Excel. If prompted to activate, sign in with the same Microsoft account used in step 2 (do not enter a product key).

    If the purchase was made as a digital download from Microsoft Store instead:

    1. Go to Order history: https://account.microsoft.com/billing/orders and sign in if prompted.
    2. Find the Microsoft 365 order, select Install (or Product key/install if shown), and follow the instructions.
    3. Let the wizard finish installing Office in the background.

    If a pre‑paid card was used and already redeemed:

    1. Go to Services & subscriptions: https://account.microsoft.com/services and sign in.
    2. Find the Microsoft 365 subscription and select Install.
    3. Complete the installation as above.

    If any app still prompts for a product key, close that prompt and instead choose the option to Sign in and use the Microsoft account associated with the subscription.
