Windows Installer

Applies To: Windows Server 2008

Microsoft Windows Installer (MSI) is an installation and configuration service that provides a standard format for component management and enables network administrators to deploy corporate servers very efficiently.


The following is a list of all aspects that are part of this managed entity:

Name Description

Windows Installer Application Installation

Microsoft Windows Installer is used to install applications on a computer.

Windows Installer Application Servicing

Microsoft Windows Installer can upgrade an application that has been installed by the installer. It does this by reinstalling an updated installation package or by applying a Windows Installer patch to the application. The installer can update the Microsoft Installer file (MSI), the application files themselves, and application registration information.

Windows Installer Environment Variables Refresh

Microsoft Windows Installer can refresh environment variables that get updated during the installation of an application.

Windows Installer Service Availability

The Windows Installer service is an operating system component that centrally manages application installation and configuration tasks, and also the process of uninstalling applications.

Windows Installer Software Restriction Policies

Software restriction policies provide network administrators with a mechanism for identifying software programs running on computers in a domain, and controls the ability of those programs to execute. These policies can thus improve system integrity and manageability.

Windows Installer System Restart

Microsoft Windows Installer can determine when a restart of the computer is necessary and automatically prompt the user to restart it immediately after an application has been installed. This usually occurs if the installer needs to replace any files that are in use during the installation.

Windows Installer Windows Resource Protection

Windows Resource Protection (WRP) helps protect your operating system by preventing the replacement of essential system files, folders, and registry keys that are installed as part of Windows. Protecting these resources helps prevent application and operating system failures.
