A. You're not alone, Lori. I've heard dozens of complaints about the lack of a Start button in Windows 8. This mainstay of computing for almost two decades is replaced by an interactive Start screen in Microsoft's newest operating system.
The Start screen uses the Modern interface that Microsoft uses on mobile gadgets. It's more touch-screen friendly and customizable. However, many people who have upgraded are a bit overwhelmed by it.
This is one of many changes that confuses longtime Windows users. That's why I wrote my Essential Windows 8 Quick Start Guide. It's a great roadmap that will help you deal with all of Windows 8's quirks.
