Installed new motherboard, cpu, ram, and gpu, and now my version of windows 10 is not activated

Hello everyone to start off the specs of my rig are:

Corsair 850w gold
Wd 1 tb HDD
samsung 120gb SSD
DIYPC full atx case
Z170a msi MOBO
Intel I5 6600k overclocked to 4.6
xfx Radeon rx 480 8gb version

So my problem is as follows
I recently upgraded my rig with the gpu and cpu mogherboard and ram and everything is running great.

Unfortunately by swithing out my motherboard i have effectively deactivated my version of windows 10, now if i bought windows 10 i would have a product key i could just plug in to fix this problem, unfortunately i was one of the people that upgraded from windows 7 about a year ago, now when i log in to windows i cant personalize my pc and i have that annoying watermark "activate windows" in the bottom right corner of my screen overlaying over all my games, i researched the Internet on how to fix this issue and they said to call microsoft, explain what happened and they would fix it, i did this and spent a half hour on the phone to which I recieved the answer that there is nothing they could do about it and i needed to call the people i bought my os from "the windows 7 oem disc" to fix it well its been 4 years since i built this pc so i have no clue where i bought the os disc from, i still have the os disc but cant find the damn product key i used to have with the disc its not on the box, so i was wondering what i can do to fix this issue, thank you all its very much appreciated.

Microsoft see a new CPU & Motherboard as a new PC. You replaced so much I can see their point.

Best fix is buy a new licence. Get a retail licence and it can move to new PC. That is big difference between OEM & Retail.

Not sure why Microsoft are telling you to chase people you bought software off 4 years ago. They should know you cannot reuse an OEM key that is tied to last motherboard/CPU. Not yet anyway. They haven't signlaed that is likely to change that much.

If you had done this in a few weeks, Microsoft are changing the way activation works so a new motherboard won't auto deactivate win 10. But you changed over half the PC, so it stands to reason that this would have set off deactivation even in that case.
