Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
The Office 365 / Microsoft 365 subscription is completely separate from BitLocker and from any reset or clean install of Windows. Cleaning or reinstalling the computer because of BitLocker does not cancel or consume the subscription.
If the subscription was renewed successfully, it remains valid for the full term that was paid for, and it can be used again on the same device after reinstalling Windows or on a different device signed in with the same Microsoft account.
To confirm the status before paying anything again:
- Go to the Microsoft account subscriptions page and check that the Microsoft 365 subscription shows as active and verify the expiration date.
- If the expiration date or status does not look correct, contact Microsoft Support for subscription/billing help.
In the meantime, if there is any issue installing the desktop apps, Office Online can be used for free in a browser at Office.com.
