The Start menu makes its return in Windows 10 after being banished from Windows 8. But it’s not like the Start menus of Windows past; instead, it’s more of a mashup of the traditional Start menu with Windows 8’s live tile-infused Start screen. And believe it or not, it can actually help you process information faster.
Windows Store apps and most default Windows 10 apps can be configured to show updates and highlights right on your Start menu -- an especially useful feature for the Calendar, Mail, and News apps. Live tiles are enabled by default, though you can toggle the functionality on and off by right-clicking on a tile in your Start menu and selecting More > Turn live tile on/off.
Even if you don’t appreciate the flashy live tiles, take the time to arrange your Start menu so that your most-used programs are front and center. That’ll save you precious navigation time if you don’t pin programs to your taskbar -- it also helps keep your secondary software organized even if you do pin your most-used programs. Rearranging Start menu tiles is a simple drag-and-drop affair.
