Hello,
Thank you for reaching out. I am Harun an Independent Advisor and Microsoft User. I will gladly help you out.
There are few ways to confirm if your version is Genuine or not. The first one you used shows that your Windows is Genuine.
The Line Description saying that Your Windows is: OEM version and Not anything starting with VOLUME_.... that would be a software or crack that would leave such entry.
PS: Product keys are issued by the original equipment manufacturer (OEM) and are not-for-resale and may not be transferred to another computer. They may, however, be transferred with the computer if the computer is transferred to new ownership. If the OEM PC came preinstalled with Windows 10, then the product key will be embedded in the UEFI firmware chip.
A Second and more easier way is to perform Windows genuine validation via Settings. Just go to the Start menu, click Settings, then click Update & security. Then, navigate to the Activation section to see if the OS is activated. If yes, and it shows "Windows is activated with a digital license ", your Windows 10 is genuine.
Please feel free to ask for more Information and let me know if this helps.
Sincerely
Independent Advisor
