Recently i bought a laptop, but it had a major issue with it and that was a hard drive failure, soon the company replaced the hard drive but did not install the OS, now buying an OS from Microsoft would cost me a lot of money so i did not have that much money left in me, so i did some research and found this site, I paid through paypal and they gave me the key and download link via e-mail. Although i wish that they would have sent me quicker. But nevertheless it works fine for now and windows says that the key is genuine. So look no further go ahead and buy it
