Different Security Levels in Windows® 7 System
A new User Account Control (UAC) user interface has been introduced, which provides the ability to select four different levels of security notifications in Windows 7. It aims to improve the security of Windows 7 by limiting the application software to the user privileges until an administrator gives an upgrade. This separation of allowed and denied tasks within Windows 7 is controlled by a slider providing different levels of security and actions to be set on each desktop. In the high level of security it always notifies on every system changes. The UAC prompt results when any system-level change is made,like any software installation etc. In the medium level it notifies you only when programs try to make changes to your computer. This level of setting does not prompt when users change Windows settings, such as 'Control panel' and administration tasks. Another level of security is the low level that never notifies the users and turns off UAC altogether.
