Windows 8.1 changes and improves upon some of the features of Windows 8. Windows 8.1 boots to the Start screen by default. But, if you would like to boot directly to the Desktop instead, you just have to change the settings. Move your pointer to the right of your screen to open the Charms bar, and click Settings. Select Personalize, and select Taskbar and Navigation from the Personalization box. Choose the Navigation tab, and check When I sign in or close all apps on screen, go to the desktop instead of Start from the Start screen section.
File Explorer now opens by default to the This PC hub, which replaces My Computer. This PC contains Folders, Devices and drives, and Network locations. You can also access your Favorites and SkyDrive from the left pane. Click the File Explorer icon on the Taskbar to access these locations.
