If it sounds too good to be true…
You can’t tell from a license key whether it’s retail or OEM as far as I know, but Microsoft puts the value of that particular license at $6,155. As a consumer, you can get away with that in most cases (to be honest, if you want a cheap Windows 10 key, just install a pirated version of Windows 7 and run the upgrade procedure, you’ll get a legitimate key for free). But as a company, it’s a lot more complicated and audit penalties are huge. If you really want to put the company you work for in that position, you’re free to do so, but I doubt you’ll get away with it. It’s quite a responsibility to take on, one I would personally not want to have.
Tbh, most of the Windows 10 keys they sell are generated by installing pirated Windows 7 copies and then upgrading, stripping the license key from the freshly installed OS.
