Microsoft Shrinks Updates
Microsoft Wednesday began adding code to Windows XP users' PCs that it said will reduce the time it takes future updates to download, a potential boon to those connecting to the Internet via dial-up connections. The program, called Package Installer, has previously been part of every update downloaded and installed through the Windows Update site and the Automatic Updates service. By putting the files on each PC, Microsoft said "subsequent updates can have a significantly smaller download size."
Although the Package Installer download is currently classified only as "critical" by Microsoft, and thus optional, it will shortly be made mandatory. As soon as that happens, updates retrieved from Windows Update or through Automatic Updates will require that the files be on the local machine.
Package Installer can be downloaded manually from the Microsoft Web site or by using the Windows Update site.
