Hello everyone,
We would suggest you to migrate to the latest version of Windows 10 as soon as possible to avoid potential cyber attacks. Incase you are unable to migrate on time or reluctant to upgrade, you can purchase and avail the Extended Security Updates (ESUs) that Microsoft offers for these versions of OSes.
For more details regarding the ESUs and how you can deploy them seamlessly in your environment after purchasing them, refer the following article

Subscribe right away and stay updated on how to handle ESUs using patch management.
Cheers,
