This new technology is known as User Account Control. This will ask the user for confirmation before any action that would require higher privileges is performed. User Account Control is designed to prevent events from taking place without user consent, a feature which was absent from previous versions of Windows. Windows Vista also offers a protected mode for Internet Explorer 7.0 to make web surfing safer. In this mode, the browser works with a certain set of system restrictions that prevent malicious code from modifying key system areas. This does not protect against all types of attack, but reduces their likelihood. Internet Explorer 7.0 is also available for Windows XP, but without the option of protected mode
