You can remove them. They are only needed for Office 2007 add-ins.

just bought a new laptop; plan to load office 2003 (don't like 2007 - too
many keystrokes for things i used to do in one!). new laptop came with office
2007 pia (primary interop assemblies) already installed. Is taht something
for developers or the common business user? Since I'm not using 2007, can i
remove this?
Thanks
