Also asked, what does OEM Windows 10 mean?
original equipment manufacturer
Beside above, do I have OEM Windows 10? If your PC came preinstalled with a genuine Windows 10 license, then it likely has OEM license. Unlike the retail license, OEM license cannot be transferred from one computer to another. These days, OEM product keys are embedded in the BIOS/UEFI firmware to avoid license theft.
Similarly one may ask, what is difference between Windows 10 OEM and retail?
The OEM versions of Windows have been available to the general public for many, many years and have worked without problems. The main difference between OEM and Retail is that the OEM license does not allow moving the OS to a different computer, once it is installed. Other than this, they are the same OS.
Are Windows 10 OEM keys legit?
OEM keys are keys used by PC makers, normally. When an end-user uses an OEM key, this is a direct violation of the Microsoft Software Licensing Terms, but Microsoft will generally close its eyes, and the Licensing Servers will mark your copy of Windows as legit activated.
