Windows 10 has caused certain games not to play or show poor graphics such as Bus Driver,City Life 2008,Sim City Societies,Bus Simulator ,and no doubtothers such as Truck Simulator,Farming Simulator.Cant do Need for Speed or other racing games either. When upgraded from Windows 8 to 8.1 it couldnt play Ford Racing now windows 10 has buggered up most of my other games.Wont accept screen res,Haven got back up discs for Windows 8 so cant revert.In fact XP was the best and would like to revert to this!Also Outlook no longer cuts and pastes text like the old Hotmail used to which is irritating
