VistaXP v2 VS
Creating the look of Vista on XP has become something of a cottage industry, mainly because most people know that Vista IS XP just with a few fancy skins on.
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. The package is inspired by the original Windows Vista look (Codename Longhorn) and the package contains two Visual Styles - Black and Silver. The Start menu (which incidentally I hate in Vista) is very realistic and manages to compact all your programs into a shorter Star menu bar than you usually get with XP. There are only 3 different fonts to choose from which surely could have been increased although fonts are not the most important thing when it comes to the look and feel of your operating system. However, it does feature the original Segoe UI font 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, this could make a really impressive Vista look.
A very good Vista skin for XP although it lacks realism in some aspects but for free, you can't complain.
