Yo guys, I have installed windows 10 technical preview and i thought it is good but after finding out that it does not allow me to play any of my favorite games, i'd like to uninstall it, I googled it a lot and never found any useful answer, all answers were about restarting my pc - selecting windows rollback but i do not have this option, I do not even get it. I had this option before and when i tried it, it required a USB Drive with 16GB+ free space and I do not even have a USB drive, however, I do not get this option anymore, any suggestions?
