I told you that I’d decided to stop pining away for the Start Menu and take a closer look at what’s available in Windows 8.1. I started by investigation with the Apps view and its new features, such as the new sorting feature, the ability to configure it as the target of the Start button, and the ability to increase the number of icons that it can display. I then showed you how to configure and use the Apps view as a Start Menu replacement. While this works quite well, I carried my experimentation a bit further over the last few days and have found that there are several new enhancements to the Start Screen that you can use to make it look and feel more like the Start Menu. In this article, I’ll show you what I discovered.
