You should get windows 10 when it comes out fully next year, but right now it is still in development. Windows 7 is great, so for now you should use that, but windows 10 will be excellent from what I can tell when it is no longer in development, but it has many bugs they need to work out. I like windows ten because it has all the good features of windows 8 and they fixed the bad ones.
I have used windows 10 preview and own a windows 7 pc so this is just my opinion and I have all the details. Hope this helps.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
