The easy way for you to get Windows 7 is to upgrade your Windows 8 to Windows 8 Pro. The ask M$ for downgrade rights to 7. That keeps everything legal.
Hehe. Don't be so paranoid. You'll get used to it in no time.
However if you are really desperate about that start button (which is the only UI difference besides the mat glass look) you can install start8 which will bring the start button back. And one more thing. W8 uses 0.3GB of RAM instead of W7's 1.3GB and it's startup is super fast.
But if you are REALLY desperate and have a good reason then buy a windows 7 license, install them and do whatever you want to do.
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.
