Known issues with this security update
- When you install this security update on a computer that is running Windows Vista or Windows Server 2008, you may have to restart the computer two times to complete the installation. This issue may occur if you install an XML Core Services 4.0–based update together with an update that contains inbox drivers. For example, the following updates contain inbox drivers:956697 Windows Server 2008 Hyper-V VSS writer is not used during a backup job because of corrupted or invalid virtual machine configuration filesThis issue occurs because Microsoft Windows Installer (MSI)-based installations will not continue while inbox drivers are updating. This is because inbox drivers set the "impactful transaction" flag and the "reboot required" flag at the servicing stack level for Windows Vista and for Windows Server 2008. Therefore, the update for XML Core Services 4.0 will fail during installation if an update that contains an inbox driver is applied first. After the inbox driver is installed, and the computer is restarted, the installation of security update for XML Core Services 4.0 will succeed. However, an additional restart is required to complete the installation.

To avoid this issue, install the security update for XML Core Services 4.0 before you install the update that contains inbox drivers.
