User Account Control (UAC) of Vista is designed to protect your PC from accidentally installing or even running unwanted programs such as viruses, spy ware, ad ware or other harmful softwares. VISTA designed it, so you are alerted before you can take action on any program. It’s a great tool for those who like it and for those who don’t, it’s annoying. Considering that you have a solid Anti-virus program fully updated on a regular basis, same condition with Windows Defender and any other security programs you may have installed, turning off the UAC shouldn’t be so alarming. Although, It’s always best to keep it on. When this feature is activated, you are given this dialog box:

The program you are about to run would be displayed in the middle so you can know which program you are about to RUN. In this case, it shows Internet Explorer Program. Click Continue to run the program. Those who don’t want this dialog box, you can easily remove it. Just Watch a video tutorial or read the steps.
