The Operating System (OS) is the core software that manages the computer hardware resources, and provides the graphical user interface and drivers to make use of them. LEVEL51 is a Microsoft named partner, and we work closely with Microsoft with only genuine OEM windows licenses. You can be assured your Microsoft licenses are genuine and purchased through authorized local distribution channels.
Be wary of:
1) Vendors who do not include the COA with your PC, as they have purchased stolen or unauthorized licenses.
2) Vendors who have windows 10 at +0 cost, or do not allow you to remove the value of the OS from a system build.
