Windows 10: Reinstalling Windows 11 with the help of Windows 10 OEM Product Key

Right now, I have a Laptop, which had Windows 10 when I bought it. Due to my understanding, I installed Windows 11 Insiders Preview, and after Updates, I had realise that i can't go back to the Public Windows 11. So I had only one choice, to reinstall Windows 11.Now here is my Question, is it possible to use my Laptop's Windows 10 OEM Key before I updated to Windows 11 when I didn't Installed the Insiders Preview and use that to Activate my renistalled Windows 11?I would be happy if any Expert can, Understand and Guide me, so that I won't make any Huge Mistakes.

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.
