Hello, I am not unhappy with my purchase. I did a full installation on an SSD, it is a treat. One can have the start menu by free and paid applications. I get errors in the Event Viewer that are not referenced on the net. I posted on forums, I called Microsoft, no solutions, but I have no crash. Looks like the OEM version is much different upgrades. I will wait. So despite these messages, speed is a good point and also the Store applications.
