Geheel onverwacht heeft Microsoft een patch uitgegeven voor de installer.
Hiermee kan de download-tijd van patches in de toekomst aanzienlijk
worden verkort. Hieronder een tekst van de website van het Internet Storm
Centrum (ISC) van het SANS-instituut. Plaatsingsdatum is 29 juni 2005.

=======================================

Several readers wrote to us with questions about an unexpected
notification they received yesterday from Automatic Update, asking them to
install update 898461 for Windows XP. According to Microsoft, this
update "installs a permanent copy of the Package Installer for Windows
version 6.1.22.4 on the computer so that subsequent software updates
can have a significantly smaller download size." Before this update, all
Package Installer files were downloaded every time you used "the
Windows Update site or Automatic Updates to update the computer. This
redundant download can be avoided if the installer files are made resident
on the computer, because subsequent updates can use the resident files."

ISC reader Jeff pointed out that although this update is currently marked
critical, it will shortly become mandatory. As Microsoft states in the
Knowledge Base Article, as soon as this update "becomes mandatory, no
future updates that are available from the Windows Update Web site or
through Automatic Updates will include the Package Installer for Windows."

For more information about this update, see Microsoft Knowledge Base
Article 898461. Please note that this update is only applicable to Windows
XP.
