The Vistapack, is a Shell pack, based on the XPize installer.
Its goal is to let users of Windows 2000 and Windows XP, experience the Vista look and feel,
without paying the price in money and speed.
That's how it works in short terms.
But, it has some other advantages. Like the Reloader.
This little sub-program, runs on Windows start and checks if any files are changed.
This can happen if you got a update from Microsoft, or have visited the Windows Update site.
When it spots a changed file, it will "Reload" that file with the Vista resources again.
So on your next reboot, that file is Vista style again.
Good way of keeping your system in the Vista look and feel.
Currently, there are about 240 separate files that get modified by this pack, and I believe its one of the most extensive ones out there.
The pack comes with some nice extra's, like 32bit icon support on Windows 2000!!
Vista sound and cursor schemes, custom boot screen, and its own wallpaper.
There is more, but that's for you to see.
