I was really nervous about ordering Microsoft Windows thru Groupon because it was such an amazing deal. After I installed it, I even waited over a month to see if something bad happened. All my worries were a waste of time and energy! I had some difficulty loading it but chalk that up to "operator error"! Once I figured out how to download onto my new laptop, I've had zero issues!! Good product, great price, great experience. Overall, highly recommend!
