in my opinion ,windows 10 is very better than windows 8 , is more applicable and more stable than the windows 8 ! so if you can , upload and use windows 10 do you know how to create a bootable usb .
for me download windows 7 better than both ( 8 and 10 )

If your laptop has pretty good specs, like 2GB of RAM or more, I would upgrade to the Windows 10 platform because it is much more stable than the Windows 8.1 OS.
