De download is net geen 2 MB groot en kan in verschillende talen vanaf deze pagina worden opgehaald. De release notes laten de volgende lange lijst aan veranderingen zien:
New features in Windows Installer 3.0Issues that are addressed in Windows Installer 3.0
- Patch sequencing
With patch sequencing, a set of new or existing patches are deployed in the correct logical order, regardless of the chronological order that the patches were received in on the computer.- Removable patches
You can now remove patches that are installed with Windows Installer 3.0 if they are marked as removable in the patch package. Patch removal enables the patched program to be returned to the state that the program was in before the patch was applied.- More efficient patching
Several improvements have been made to patching in this release. These improvements include the following:- You can double-click a patch file to apply it.
- Patches are smaller and more reliable.
- Delta compression patches no longer require the source media.
- You can install multiple patches in one transaction.
- You can install patches that are targeted to different products in a single transaction.
- Non-administrator patches and patch elevation
User with Limited accounts can now apply patches that have been marked as trusted by the system administrator.- Source list APIs and inventory management APIs
With new source list APIs, system administrators can easily examine and change the list of source locations that are registered with the Windows Installer. Windows Installer 3.0 also supports rich product, feature, component, and patch inventory queries through new inventory management APIs. Users with privileged accounts can use these APIs to enumerate across all user and installation contexts.- Standard command-line options
To ease program deployment, the Windows Installer supports standard, easy-to-understand command-line options that control display and restart behavior, and the installation, removal, logging, and application of updates. Windows Installer 2.0 command-line options will continue to be supported and can be used with new command-line options. The following new command-line options are supported:Windows Installer 3.0 also supports the msiexec /? option. You can use this option to display all the command-line parameters that are available in Windows Installer 3.0.

The Add or Remove Programs feature in Control Panel now lets users view and interact with the installed updates to programs. With Windows XP SP2, users can select a single check box to view program updates and their relationship to a program. Updates are now grouped with a relevant program and include an installation date.For Windows XP users
