Each time you start programs from the Start menu, you use an interface that has not changed in 10 years! No wonder it has become more difficult to use as the number of programs has increased.
Vista Start Menu is a convenient alternative to the "Start" menu. It's now easier to find and run the program you need. Visually-based, and easy-to-use. Your applications are arranged in a table with icons divided into groups, which makes it easier to work with multiple programs.
And one more really important nuance: when you remove programs or install new ones, other icons remain in their places so you do not have to waste time looking for "drifted icons" as often happens.
