Prevent Malware With User Account Control
User Account Control (UAC) was introduced in Windows Vista as way to control administrative access to programs and settings while logged in as an administrator. Now, that may sound sort of weird if you come from the corporate world of system administration using Windows NT, 2000 or XP. Under these operating systems (nt, 2000, xp) if you were the administrator programs and system settings would launch without impedance and run with administrative privileges.
