Question regarding MCAfee activation after factory reinstall

Sir,

I have an active MCAfee Subscription for 12 months which came pre activated from dell. Now I want to Factory reset my laptop by recovery drive . I want to ask you that after factory reset my MCAfee Subscription will automatically be activated or not??

If not then how can I Activate it  as it came preactivated so I don't have any Email ID or Password to activate it

Any suggestions will be appreciated

Thanks
