Computers are great tools. However, a computer cannot, on its own, control the way in which it is used. However, this may be necessary to prevent problems, as when employees download pirated software from the web, or when students use a school computer for unintended purposes, or trade show attendees change the settings on a public computer.
User Control can prevent specified applications from starting and block access to blacklisted websites. It can also prevent access to operating system components. This keeps users from altering system stettings and changing the appearance of the desktop.
