Have you upgraded your windows? Still using Windows XP or Vista? It’s time fore Win7. Why Windows 7? You told us to make Windows simpler to use, more responsive, and full of new possibilities. We listened—and made loads of improvements. Here’s our top 10: 1.) A better desktop. Windows 7 gets you around your PC faster than ever.

Type in the Start menu search box, and you’ll see results instantly, grouped by category—documents, pictures, music, e‑mail, and programs.
