W8 is the very worst program foisted on the public in Micro$oft history. I downloaded and installed it from the Micro$oft website. It destroyed my computer! I then had it professionally installed, none of my external drives worked, it destroyed most of them. Now it will not play audio files, Dell replaced the M.B., RAM, CPU and case fan, still no audio. Stay with Windows 7, it is a far superior OS AND IT WORKS!
