Работает ли OEM-ключ Windows 10 21H2 после чистой установки?

Does the Windows 10 21H2 OEM key on your motherboard work?
I bought a used laptop with Windows 10 version 21H2 and would like to reinstall the system completely. I've heard that OEMs have the license key built into their BIOS and it is automatically activated during installation. I want to make sure that the license will work after reinstalling, and I won't have to buy a new key.
