If you bought a Windows license with your new computer, then we only use genuine Windows 10 64 bit edition on all of our systems. A COA (certificate of authenticity) with your unique Windows CD-key is affixed to the side or inside of every machine, and you will find the original Windows packaging in the motherboard box.
We do not install anything except for all the operating system Windows 10 64 bit , hardware drivers and our own desktop background.
We also perform benchmarks on all PCs to ensure that there are no complications. Which means that you will have a great out-of-the-box experience with a machine which is ready to go without having any trouble.
