Office2003: Stop regsvr'ing apps on runtime?

[GrofLuigi]

This is on live system. As per the title, mostly word and publisher (but I don't use others much) are registering themselves when they are started in HKCR/CLSID branch as WIA servers. Microsoft document imaging (and most of the other things in Office package, except for the bare applications) is not even installed, nor has ever been on this machine.

After I delete the key (HKCR/CLSID/{random_number}/localserver32, with value of the application name with path plus IMG_WIA or IMG_STI at the end), it gets recreated on next launch. Similarly, they register themselves in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\StillImage\Events\ when noone has asked them to.

Any reg entry or preference for this? Searched the Internet to no avail. Not a word anywhere. Only lame marketing touting.
