Windows 10: Is there any way to re-use a OEM Windows 10 Product Key

I am currently in the process of building a new gaming pc. I'm on a budget and don't want to have to purchase a whole new Windows 10 Product Key as they can get quite expensive. I was able to retrieve my product key using a command in the Command Prompt thingy. I want to make sure that I can re-use it on my new pc before I uninstall it and possibly loose Windows on my laptop. I've heard that you can't, and that you can re-use OEMM Channel product keys but I don't know what to believe.

my windows 10 oem didn't come with a product key

Dude, go to Newegg right now and read the questions and answers tab on Windows 10 OEM. The OEM copies that are listed there DO in fact, come on an optical disc. The flash drive ONLY comes on Retail copies.

indeed OEM's have embedded keys a OEM upgrade is for machines with OEM copies and DO NOT COME WITH A KEY! sadly many vendors confuse the two because pre-windows 10 'OEM" came with a key
a end user should always buy a Retail OR "System builder OEM" copy when it comes to windows 10 system builder is not `OEM` you can blame microsoft for the retarded terminology screw up

it sounds like the op bought a pirated copy with no key microsoft does not ship windows 10 on optical disks .... they use flash drives

It needs a key if it has never had windows 10 installed on it before.
