The best and most cost-effective way to acquire full Windows licenses is through preinstalled licenses on a new PC. Windows10 GGWA have following requirements or considerations
-Sold through Microsoft Licensing Solution or Providers or direct from Microsoft
-No transferability of license
-Placement of a one-time–only order
-Commercial Licensing downgrade rights are available
-Downgrade rights are not available; available only with an Academic Volume License
