User Account Control (UAC) and administrator rights

User Account Control (UAC) in Windows Vista restricts the user and software to change major settings. This first hurdle must prevent the system to be infected by malicious software, but makes it more difficult to install and run software as well. Although UAC makes Windows safer, for many it is annoying. This security rule frequently interrupts all activity, because every change in systemsettings must be confirmed individually by the user. Unfortunately the frequency is very high, which causes the user to click them away as fast as possible. By clicking automatically to proceed malicious software will soon pass this security test and User Account Control won't be of any use. The executalbe files and system changes which have to be confirmed by UAC can be recognized by the shown administrator shield, which informs the user about the popup which will show up.
