HFSLIP is a completely free and open code application designed specifically to update your original installation of Windows 2000, XP or 2003 with the latest patches and improvements.
The patch and improvement binaries (individual files) supported by this program are transferred directly. This is to say that the original files are directly replaced with the latest version, obtained from the same Microsoft download centre. If it finds a patch that isn`t supported or needs a special process, the HFSLIP program will integrate it directly, and will install it after the final Windows configuration.
