When I updated Windows 7 today, I noticed that it included several updates for Office 2007. However, I only have Office 2003 installed. Are these Office 2007 updates (a) for Office 2003, (b) for Visual Studio 2008, or (c) a figment of Bill Gates's imagination?
If you have any of the viewers or compatibility packs installed, that might trigger updates associated with the newer version of Office. Upon getting certain attachments in Exchange I was prompted to download a compatibility pack in order to view the document. After this I would see 2007 related Updates in my 2003 Office install. I would also see the updates when I only had Visio Viewer installed.
Link to the Compatibility Pack which may be installed: http://www.microsoft.com/downloads/details.aspx?FamilyId=941B3470-3AE9-4AEE-8F43-C6BB74CD1466&displaylang=en

I had Visio Viewer installed, then later deleted, and sill would require the Update. I'm assuming this is because some DLL's were left behind.
