I have flashed my windows 7 to windows 10.1, I havenot used windows 8 as it was not much user friendly and the UI is also not as good as windows 7 after using windows 10 I felt like that this is a combained version 7& 8 with assistant. It supports all the softwares like its previous version. The space consumed by os is less compared to the previous versions. Apart from all the positive’s above, there are bugs like disconnecting and reconnecting of usb automatically, wifi bar will show not connected symbol even if it connected.
