Frequently Asked Questions

Will I lose my Microsoft 365 subscription if my old laptop breaks?

No, your Microsoft 365 subscription is tied to your Microsoft account, not your physical hardware. You can easily install it on a replacement device by logging into your account online.

Do I need a new product key to install Office on a replacement computer?

No, you do not need a new product key. As long as you have an active Microsoft 365 Family subscription, you simply need to sign in with the associated Microsoft account to download and activate the software.

How do I ensure my OneDrive files sync correctly to the new laptop?

Ensure you sign into the OneDrive app on the new laptop using the exact same Microsoft account that was used on the old laptop. Once signed in, OneDrive will automatically begin syncing your cloud files to the new device.

Does a broken computer delete my OneDrive cloud files?

No. Files that were already successfully synced to OneDrive are stored securely on Microsoft's cloud servers. A hardware failure on a local device will not delete or overwrite your cloud data.
