Microsoft 365 subscriptions are tied to the Microsoft account used to buy the subscription, not to one specific laptop. A new subscription is not needed.
Try this:
- On the new laptop, go to https://www.office.com and sign in with the same Microsoft account that was used to purchase Microsoft 365.
- Select Install apps to download the installer.
- Run the installer and complete the setup.
- Open Word, Excel, or another Office app, then sign in with the same Microsoft account to activate Microsoft 365.
If Microsoft 365 is still active on the old laptop and there is a device/sign-in limit issue, check the subscription at https://account.microsoft.com/services. Under the Microsoft 365 subscription, use Manage to review devices or sign out of Office on the old device, then sign in again on the new laptop.
To confirm where the subscription is managed:
- If Manage, Cancel, or Change payment appears on the Microsoft account subscriptions page, the subscription is billed by Microsoft and can be managed there.
- If those options are missing, the subscription may be managed by a third party such as Apple, Google, or a retailer, and billing changes must be handled with that provider.
If the subscription is Microsoft 365 Family, Personal, Premium, or Pro, the desktop apps can be installed on Mac or PC.
