XPize is a GUI enhancer that replaces most of the non-XP icons, avis and bmps that Microsoft has always overlooked. It also includes some extras and a reloader, which you can use after visiting Windows Update.

xpize is a utility program for Windows XP (32-bit only) and Windows Server 2003 (32-bit only) that replaces most of the bits in Windows that didn't match XP's style with bits that do.
The software contains no spyware or adware, it is a purely volunteer-driven community effort; it is also easily uninstallable.
xpize does not replace any files, system or otherwise. Instead it "patches" the files by replacing the old resources inside the files.

The license of this software is Free Trial Software, you can free download and get a free trial.
