I just received my new computer, and it came with a Microsoft 365 subscription. Can I use that to extend my subscription that I already have?

Hello Rebecca Burton,

Thank you for reaching out in Microsoft Q&A forum

I understand you want to know whether the Microsoft 365 offer that came with your new computer can be used to extend your existing subscription.

It depends on the type of offer included with the PC:

If the PC includes a Microsoft 365 product key

  • You’ll receive a 25‑character key (either printed, emailed, or shown in your device setup).
  • When you redeem it at https://setup.office.com/, the extra time adds (stacks) onto your current subscription as long as you use the same Microsoft account.

If the PC includes a Microsoft 365 trial (common on new computers)

  • This is often a 1‑month or 3‑month trial.
  • No product key is provided.
  • It cannot extend a paid subscription. It simply starts a separate trial on your account.

If the PC includes a “Microsoft 365 included” OEM offer

(Sometimes labeled as “1-year included,” “device offer,” or shown during Windows setup)

  • Activation happens automatically through the device, not through a key.
  • These offers do not stack with an existing subscription.
  • They create a separate plan attached to the Microsoft account used on the device.

How to check what you received

  • Look for a 25-character key → this can extend your subscription.
  • If there’s no key, then it’s a trial or device-bound offer → this cannot extend your existing plan.

If the current Office product was provided by the PC manufacturer or the seller as a prepaid one-year subscription, you may not be able to extend it with a newly purchased subscription.

To extend your Microsoft 365 subscription using the subscription offer that came with your new computer, you typically need to redeem the product key associated with that offer. Here are the general steps to follow:

  1. Check your current subscription status: Ensure that your existing subscription is active and not expired.
  2. Redeem the product key: You can redeem the new subscription offer by going to the Microsoft 365 admin center and entering the product key.
  3. Choose how to apply the new subscription: Depending on your situation, you can either renew your existing subscription for an additional year or add licenses to your current subscription, which may extend the end date.

Make sure to follow the specific instructions provided with the subscription offer that came with your computer, as there may be unique steps or conditions associated with it.
