A title bar for Windows Store apps
When you're using a mouse with Windows 8, the gestures to close or minimize a Windows Store app aren't obvious. Windows 8.1 Update 1 changes their behavior slightly by adding a title bar with Minimize and Close buttons, along with an icon at the left that reveals window-arranging options when clicked. The new title bar appears briefly when a Windows Store app opens for the first time, and it reappears when you move the mouse pointer to the top of the screen.
Taskbar options when multiple apps are open
The newly unified taskbar is available even when two or more Windows Store apps are arranged on the screen. Here, the Reader app is displaying a PDF document on the left, with a web page open in the "immersive" Internet Explorer 11 on the right. Moving the mouse pointer to the bottom of the screen makes this taskbar visible, and clicking any icon opens that program, giving you the option of where to position it on the screen.
Fine-tuning for Internet Explorer 11
Internet Explorer 11 gets a significant refresh as part of Windows 8.1 Update 1. The Reading View button, previously only an icon, adds the word "Read" to make its function more obvious. The Tools menu, available by clicking or tapping the wrench icon, now includes an Options choice, which eliminates the need to open the Charms menu and click Settings.
