We love windows 10. Windows 8 sucked big time. We liked the app store but liked the ease of windows 7 way more. Windows 10 married those two very well in our opinion.
I'm sure some of you will disagree with me, but Bandicam is the best recording software that you can get for free... besides Nvidia recorder.. which you'd need a GTX 580+ to get it. To reduce bandicam lag, make a manual recording window around your minecraft game. That'll help reduce the lag more than having the actual game recorded. Fraps drops your FPS significantly depending on your computer. I have 2 GTX 970s in SLI configuration so I have no problem running fraps or bandicam.
