Microsoft has released an update to Microsoft Office 2000. By installing this optional update, the MsiFileHash table for your Microsoft Office product is updated. Updating the MsiFileHash table will help Office reduce the chance that the Office Setup program will need access to your Office 2000 source CD-ROM when you install Office updates in certain scenarios. Additionally, by updating the MsiFileHash table, the need to copy files from your source will be reduced, resulting in faster file copy (when necessary) and reduced network traffic (when applicable).

Windows Installer update requirements
Both Microsoft Windows XP and Microsoft Windows 2000 Service Pack 3 (SP3) include Windows Installer 2.0 or later. To install the latest version of the Windows Installer, visit one of the following Microsoft Web sites:
Windows Installer for Microsoft Windows 95, Microsoft Windows 98, and Microsoft Windows Millennium Edition (Me):
When you use the Microsoft Office Updates Web site to install Office 2000 updates, you may have to have access to your original Office 2000 source files such as the Office 2000 CD-ROM. The update routine may have to access the source files from your installation source. For example, if you installed Office 2000 from the Office 2000 CD, the update may have to have access to the CD that you used when you installed Office 2000.
The reason behind this behavior is that the updates from the Office Update Web site are named “binary” updates. These updates do not replace files--for example, .dll files and .exe files. Instead, the updates actually update pieces inside the .dll files and .exe files. To do this, you may have to access the original file so that the original file and the binary updates can successfully combine to make the updated file that is installed on the computer.

The Office 2000 Update: KB835220 is a special update that basically silences the need for the Office 2000 source files in certain circumstances.
This update prevents the unnecessary copying of files that have not changed. This prevents a request for a file to be copied even though it has not changed. The Windows Installer did this originally because it could not detect when unversioned files may or may not have been corrupted.
For best results, when you use this tool, future updates will use full-file updates instead of the binary update. A full-file update is better because it will provide the whole new file for the files that have changed. If the current version of the file is the same as the original file, there is no need to include it in the update. When this update is combined with full-file updates, a source will only be needed for files that are damaged or are missing, and that are not included in the full-file update.
