VistaXP v2 VS is an excellent Vista skin for XP which gives you all the benefits of the Vista look, without paying hundreds of dollars for the upgrade.
VistaXP v2 VS is inspired by the original Windows Vista look (Codename Longhorn) and the package contains two visual styles - Black and Silver. The Start menu is very realistic and manages to compact all your programs into a shorter start menu than you usually get with XP.
There are only 3 different fonts to choose from in VistaXP v2 VS, but there surely could have been more. It does feature the original Segoe UI font, however, although the wallpaper is limited to the now rather dated Vista Beta 1 wallpaper. It's a shame the developer chose not to include any widgets in this pack as that would really have made it much more realistic, but combined with another Vista skin pack, VistaXP v2 VS could help create a really impressive Vista look.
VistaXP v2 VS is a very good Vista skin for XP - although it lacks realism in some aspects, it's for free, so you can't really complain.
