Info (c) Microsoft:
A user account determines how you interact with your PC and personalize it. For example, your account determines which files and folders you can access, the changes you can make to the PC, and your personal preferences, such as your desktop background or screen saver. If you create separate accounts for other people, they don't have to share the same settings, which means you can restrict access to your files, folders, and even give different desktop backgrounds to other accounts.
