ViStart is a free program which will convert your boring looking xp start menu to the amazing looking vista start menu, it comes with all those features of vista start menu like search programs right away from start menu, fading menu icons and also have Multilanguage support for non english users
ViStart menu skin looks exactly like windows vista start menu and it also supports third party skins made at deviantart.
One of the most amazing feature I liked in windows 7 is it most useful and productive taskbar which consist of iconized taskbar items which can rearranged when and how you feel like arranging them.
The most amazing thing about the windows 7 taskbar is that it no longer displays the name of the programs, on the other hand it displays only icons by default which provides more space for other programs and opened windows to fit in
It will replace the normal taskbar of windows xp with this windows 7 like taskbar which is more beautiful and manageable for different windows and applications opened. It provide more space and good look feel as compared to the boring looks of windows xp taskbar.
