Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi
Thank you for posting the thread on our forum.
Based on your description, It seems that you want to know what is Digital licence.
Digital licence, previously called Digital Entitlement, when a computer is upgraded from a previous version of Windows; it receives a unique signature of the computer, which is stored on Microsoft Activation Servers. The Windows 7 or Windows 8 genuine license your system was previously running is exchanged for a diagnostics key.
With Digital License, there is no need to know your product key or purchase another product key if you lose it. Anytime you need to reinstall Windows 10 on the same computer, just proceed to do so using any of the available options. Windows 10 will automatically reactivate without asking questions.
If many features was disabled when you sgn in Office, it maybe because you haven't activate your office, please sign in www.office.com >Account>Subscriptions>to see if you have license: the latest version of office desktop
You can link your Microsoft account with your digital license enables you to reactivate Windows using the Activation troubleshooter whenever you make a significant hardware change.
Besides, if you want to get Lifetime Validity For MS Office, you can buy the subscription of office , then you can always get it, and if your account subscription will be expired , remember to buy a new subscription to keep your account activation. You can refer to Manage your Microsoft 365 subscription

Your understanding and patience will be highly appreciated! Hope you have a good day and keep safe!
