Vista Transformation Pack will give to your Windows XP system the new and cool look of Microsoft’s future operating system: Windows Vista.

The pack changes most of the system icons, skins and toolbars and also adds new enhancements to your desktop such as a dock bar or a different system tray clock. It is free and does a great job of giving machine a look similar to Vista.
It does have uninstallation options in case you decide you want to get rid of it, so there really isn’t anything to lose. However, when you install the software it has to overwrite some system files (it modifies things like the boot screen) so Windows will prompt you stating that your system files have been changed. It will ask whether you want to change them back or leave them, so just leave them if you want the system to function properly.
