Remove the old computer

Locate your old Windows 10 computer in the list of linked devices and click on 'Remove device' to free up an installation slot.

Install Office on the new PC

Frequently Asked Questions

Do I need to buy a new Microsoft 365 subscription when upgrading to Windows 11?

No. Your Microsoft 365 subscription is linked to your Microsoft account, not your device or operating system. You can simply sign into your account on the new Windows 11 computer and install your applications.

Will I have to pay again if I cancel my subscription and restart it?

Yes, if you cancel a subscription and the active period ends, starting a new one will incur standard charges. Always check Microsoft's refund policy before canceling to see if you qualify for a prorated return on the unused time.

How do I fix a new subscription that won't activate?

Ensure you are signed into your Office apps with the exact Microsoft account used to purchase the new subscription. If the wrong account credentials are cached, sign out, use the Microsoft Support and Recovery Assistant to reset the activation state, and sign back in.

How can I remove my Microsoft 365 license from an old, broken computer?

You can manage your device limits remotely by signing in to account.microsoft.com/devices. From there, locate the broken computer in your list of linked hardware and select 'Remove device'.
