Windows 7 Is my Windows product key the 25-digit code on the back of the disc box?

[JohnJSal]

I'm a little wary of using third-party software to search for my product key, but I'm pretty sure the Windows disc (and box) I have is the one I used to install it all those years ago. Is this the key I need when installing Windows 10?

It's an OEM version, but I installed it myself, so I don't think it came on the HDD already. I've read that the key could be different than the one on the box if it was pre-installed by the manufacturer.

I also found something called the "Product ID" in the Systems settings, but that doesn't have a full 25 digits, and it also has "OEM" in the middle of the ID, so I don't think that's the actual activation key.

Thanks!

Yes, product keys are a series of 25 characters in 5 groups. They contain letters and numbers.

Product keys haven't come on stickers on PC's since the Windows 7 days.
