What is the best practice for activating/deactivating BIAB? I notice in my user account that 2015 and 2016 show active registrations. 2015 is no longer on the system with 2016 installed and I will update to 2017 in the next week. So should I deactivate 2016 before installing 2017? Or just let activations pile up my account?

Also a recent Windows 10 update had me calling support to re-activate/register 2016 so I expect MS will step on me again but that's another issue!!

Thanks for guidance.
