VistaMizer

Vistamizer is a program that allows those running Windows XP to have the appearance of Windows Vista. If users like the look of Vista, but want to keep the core of their systems XP, they simply have to install this easy-to-use program. In other words, they can change the look, but keep the foundation.
The Vistamizer allows users to transform their Windows XP systems by adding the transparencies, new icons, 3D effects and all of the other eye candy that came with Vista, while retaining the core XP system. The program is easy-to-use, only requiring that you hit the “Next” button a few times and then restarting your computer. If you want to go back to the XP look, the program saves a restoration point so you can set your system back to the original XP look, if you should so ever desire to. Vistamizer lets the user select which elements they want to change and which to leave the same.
If you want to change any of these elements back, you will have to run the Vistamizer uninstall process. One of the drawbacks to Vistamizer is that some of the icons do not display as they are supposed to. If you want to modify the look of your system to Vista, but keep you XP, Vistamizer is a good program to use.
