Microsoft Windows Server 2012 R2 Standard - license

The Windows Reseller Option Kit (ROK) is a software distribution option that enables you to order tuned and certified Microsoft server software separately from OEM servers so that you have more flexibility to deliver customized server solutions. Each ROK is another server option that you can specify when you order servers. You can install the appropriate ROK on your customer's preferred server model. Customers still enjoy the same great performance of OEM-tuned drivers for Microsoft Software, because each ROK is carefully matched to a specific server brand.

By purchasing your Windows ROK from Lenovo, you have a convenient one-stop-shop for clients, servers, and operating systems. You can enjoy a fast, easy method to purchase affordable servers and options with a Microsoft Windows compatible operating system. Lenovo and Microsoft work together to ensure that ThinkServers and Windows Server deliver optimal performance and work together seamlessly.
