System Mechanic Ultimate Defense is not offered as a lifetime product, only System Mechanic and System Mechanic Professional.
What happens if you upgrade from Lifetime to System Mechanic Ultimate Defense?
As a System Mechanic Lifetime customer, after you purchase System Mechanic Ultimate Defense, you will receive a new activation key that provides full access to the product as an annual renewing subscription service.
Your existing System Mechanic or System Mechanic Pro Lifetime activation key will not change and will continue to be active so that you can revert to using it at any time, especially should you decide not to renew the System Mechanic Ultimate Defense subscription in the future.
For example, if after a year of enjoying the benefits of System Mechanic Ultimate Defense you decide not to renew the subscription, you will be able to resume use of your System Mechanic Lifetime product.
Why does System Mechanic Ultimate Defense show two keys?
If you had originally installed and activated the product as lifetime, System Mechanic Ultimate Defense will retain your key and automatically revert to using it should your annual subscription expire.
