I have two Windows Installations on the same machine

I have two plain parallel Windows Installations on the same machine (no virtzualization) and a shared data drive. So no matter which Windows Installation I am booting I will have my email.
So I tried this a couple of years ago and Emclient always wanted to be reactivated after rebooting with the other OS (on the same computer).

Is this problem solved by now?
That will be the major point before I would go for Pro.

You will either need 2 licenses, or reactivate each time.

That is because the separate Windows installations are separate machines and they have different hardware IDs.
