Windows 7 log in screen changed. How can I change it back?

Open Desktop Background by clicking the Start button , clicking Control Panel, clicking Appearance and Personalization, clicking Personalization, and then clicking Desktop Background. Click the picture or color you want for your desktop background. If the picture you want to use is not in the list of desktop background pictures, click the Picture location down arrow to view other categories, or click Browse to search for the picture on your computer.

When you find the picture you want, double-click it. It will become your desktop background and appear in the list of desktop backgrounds. Under How should the picture be positioned, choose to have the picture fit the screen, tile, or be centered on the screen, and then click OK.

Easy, you just go to google images, type in what you want as your wallpaper in the bar, click the full size image of what you want, RIGHT click, they it should say set as wallpaper/background. 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.
