Windows 10: Upgrade doubt

If I purchase Windows 10 Home from official Microsoft website and I got installed on my desktop. But if in future I upgrade the system like cpu, motherboard change then will my previous installed windows will work with my upgraded system?

Recovery Drive Doubt

I created a recovery drive usb pendrive when i bought my laptop. That time it was Win 10 Home SL. Now i upgraded it to Win 10 Pro and activated it using "illegal software". So these are the doubts which i have :

1. Can the Recovery Drive reverts Pro to Home? (Recovery Drive was created during Win 10 Home SL. So if i boot Recovery Drive it should revert back to Home. These are my thoughts)
2. Will the digital license work after downgrading ?
3. Will there be any backlash ?

P.S. After upgrading it to Pro, there was a warning saying "digital license valid for Home SL, and not for Pro". I used an "illegal software" to activate it. Also i am a newbie so please explain it step by step.

Video card or RAM need upgrading?

Memtest: no errors after 10 hrs.
I'm going to perform the Primetest, later on. Get back to you on that.
I'm going to take it step by step, guys. I need to find the problem with this current computer. I might have to upgrade some components, so that it is still runnable. As for the new one, yes....i will build on it later. I need to find something decent 'gaming experience', all suggestions appreciated. THanks.
