The default local user accounts are built-in accounts that are created automatically when you install Windows.
After Windows is installed, the default local user accounts cannot be removed or deleted. In addition, default local user accounts do not provide access to network resources.
Default local user accounts are used to manage access to the local server’s resources based on the rights and permissions that are assigned to the account. The default local user accounts, and the local user accounts that you create, are located in the Users folder. The Users folder is located in the Local Users and Groups folder in the local Computer Management Microsoft Management Console (MMC).
