  • It improves the stability of Windows PowerShell.
This update also resolves the following issues in Windows Vista:
  • A compatibility issue that affects some third-party antivirus software applications.
  • A reliability issue that occurs when a Windows Vista-based computer uses certain network driver configurations.

MORE INFORMATION

Known issues

  • This package has been updated to version 2. An issue was identified in which certain computers that have specific older SATA (Serial ATA) controllers that use the AHCI (Advanced Host Controller Interface) protocol and SATA-connected CD or DVD drives may not start after the installation of the original version of this package. Version 2 of this package has removed the fix that caused this problem. If you are using a computer that experienced this issue, you can restart the computer by using a bootable Windows Vista DVD and by selecting the Repair/System Recovery options. If your computer has already installed the original version of this update and has successfully restarted, you do not have to install version 2 of this update.

    Note This issue does not apply to the package that is available on Windows Update.
  • There is an issue that causes offline, unattended installations to fail. This issue does not affect users who install this package by using Windows Update or the Microsoft Download Center.

    Issue workaround
    An unattended installation fails because the package is trying to set ACLs on a directory (%windir%/prefetch) that does not exist. If you must install this package in an offline image, you can create this folder manually before the package is installed. For example, create a C:/Windows/prefetch folder before you install the package in the image.
