The advantage of using xpize compared to other programs is that it doesn't modify or replace any files that may affect the system's general functioning, it actually renovates other resources like icons, images, animations,... The process of substituting old resources for other more modern ones is done automatically and it notably improves the system's graphical interface.
During the installation you'll have the possibility to choose between different themes, among which you'll find: Media Center, Darkside, Luna Element, etc. or create one to your own taste. Together with xpize, TaskSwitchXP is also installed, this program will offer you the possibility to modify a large amount of configuration options.
And if you want to return the operating system to its original status, you'll only have to uninstall the program.
If you still use Windows XP, download xpize to adapt it to the modern trends.
