Windows 10 upgraded from Windows 7 OEM; reactivation on a new system

Greetings!

One of my desktops is based on now ancient Intel Core 2 Duo CPU. I'm currently torn between swapping the CPU for used Core 2 Quad (since other components were upgraded during the years and are decent, even by today standards), and buying the brand new motherboard, CPU and RAM, perhaps even GPU; while retaining the present SSD, HDD and other peripherals.

On the system in question, I had Windows 7 OEM (x64) originally installed which I've later upgraded for free to Windows 10. Currently, I'm running the latest version (Creator's Update).

My question is: would it be possible to reactivate Windows 10 on a new system described above given the fact that the original system was OEM version of Windows 7? I'm aware of the fact that OEM license is tied to a motherboard, but I've read somewhere online that with Windows 10 it is possible to link the license with a Microsoft account and to reactivate even the OEM version after the significant hardware change.

Can someone please confirm this so I can easier decide between trying to rejuvenate the old system or basically building the new one?

Thank you kindly for your answer.

Not sure of the answer to your specific question, but my inclination about your overall situation is that I would get off the Core 2 Quad idea and get on with something in the last generation or two for motherboards and CPU.

Core 2 quads are what, 8 years old?

Unless of course you have major budget issues or unless you have minimal need for the additional features and CPU power available in the last 2 generations. I'll grant you that something like a 2600K was a major workhorse and still suitable for a lot of situations.

Thank you for a quick answer.

Unfortunately, money is a bit of a problem, at least at the time being, hence this topic.

The PC in question is not my only system; I have another built for my primary activity: music composition and production. Since this other system cost me pretty much already, I was hoping if I could extend the life of the older one, which I use for everything else. It had served me well during a number of years, but the CPU is now certainly a bottleneck.

But if it's really time to buy a new set of components, it would be certainly helpful if I could reuse the existing Windows license instead of purchasing yet another copy of Windows (currently, I have three separate Windows 10 licenses in my household).

This is what Microsoft says about it:

Thank you for posting that article; it explain a lot, but I'm still not sure if it's relevant to my particular situation.

It is exactly your situation.

What I've meant to say earlier, is that this article doesn't specify is the reactivation possible in the case where Windows 10 isn't purchased at the store, but is upgraded from previous version which is an OEM version (Windows 7 Home, in my case). Also, it mentions only the possibility to change the motherboard. What about even more significant hardware change? I was thinking about buying a new CPU which requires a new motherboard and RAM as well. Since the budget is an issue for me at the time being, it would be an inconvenience if I buy new components mentioned while silently hoping that I can reuse one of my present Windows licenses, only to find out in the end that I have to buy a new copy, as the previous one was upgraded from Windows 7 OEM.
