Create Windows 8 User Account with Windows Live ID
Starting with Windows 8, It is now possible to have a user profile and most of the data to be synced across multiple computers if they all are used using the same Windows Live ID.
You can either connect a local Windows 8 Account to Live ID or just create another user account and use Windows Live ID for that.
You can Sync :
Personalized settings like Colors, Background, and Lock Screen, Windows 8 Themes i.e. Background Images, Sounds, Event Sounds, Ease of Access : Settings for Speech Recognition, magnifier, Language Preferences, Keyboard, display language, Windows Apps Settings. Remember not all settings can be synced, only whichever is configured by the app, Taskbar, Windows Explorer
