Upgraded two systems with different Win 8 keys to Win 10, now both have same key

[DiscostewSM]

So I first dealt with upgrading my laptop from Windows 8.1 to Windows 10. Kept having problems until I downloaded and burned a disc of it from my laptop. After that, all went well. I upgraded, grabbed the license key, and then did a fresh install.

Now I just used the same disc I burned for my laptop to upgrade my desktop system from 8.1 to 10. Upgrade went through, but for some reason, my ethernet wouldn't work. Grabbed a USB adapter to connect, and then went through the process of grabbing the license key for that too (since before plugging that in, it showed N/A. Both my systems had different legit license keys when they were running Windows 8.1.

Now here's the problem, as mentioned in the title. I check the license key derived from my upgraded desktop, and I come to find that it's the exact same key grabbed from my laptop after it was upgraded. I don't know if it's because I used the same Windows 10 installation disc to upgrade them, but in any case, this should not be, as both had different keys when running Windows 8.1.

Was I supposed to download from Microsoft's website again a copy of Windows 10 through my desktop with the tool that generates the ISO? Can I revert back to Windows 8.1 so I can do that (if that's what I needed to do)? Going from 2 separates keys with Windows 8.1 to both having the same key with Windows 10 is not my idea of a good thing, especially if it's not legal for it to be like that. I don't want Microsoft locking me out of my own system because they find two computers running the same key when their own installation made it that way.

Let me guess- it's one of these?

Windows 10 Home - YTMG3-N6DKC-DKB77-7M9GH-8HVX7
Windows 10 Home SL- BT79Q-G7N6G-PGBYW-4YWX6-6F4BT

Windows 10 Pro VL-MAK - QJNXR-7D97Q-K7WH4-RYWQ8-6MT6Y

before someone gets their panties in a twist about me posting these- these are the generic keys used for all windows 10 installs- the actual activation seems to be tied to your hardware not a key.

Windows 10 uses generic keys for activation- the actual activation is tied to your hardware somehow.
Basically, don't worry about it.

Well shoot. I should have waited for a response. After I posted, I checked up on how to revert (through Settings->Update->Restore, but just for the first month), so I figured I'll tell Microsoft why I'm reverting, thinking it was a legit problem from their end, and began rolling back. Now I'm stuck in the revert process, only to find out it wasn't an actual problem. Maybe since it showed that it was activated by giving me that key instead of N/A after connecting to the internet (Settings->Update->Activation said it was activated), perhaps I can just go ahead and do a fresh install. Already backed up my important stuff prior to the upgrade.

I wonder if it's not only the hardware, but the past license key that also gets tied into the activation.

edit:

And yes, the key derived form the upgrade is one of those

My pc is using the same key I upgraded from windows 7 Home to 10 Home

Well, this may actually suck. If they activate using hardware information and/or previous key, then what'll happen if I upgrade the hardware? A new graphics card may not be a problem, but what if it's a new MB, like if I'm replacing a bad one? This looks bad.
