As much as I like some programs to be integrated, some items just don’t seem so helpful.   What there should be is a more simple way to disable these helpful items from the program that put them there.  Such a program is the Adobe Professional ver 7 and 8.   Here are the settings to stop the PDF Maker Office Addin.   The plugin or addin is stored in the registry.  It is just a simple change of a key value “LoadBehavior” from a 3 to a 0.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\PDFMOutlook.PDFMOutlook]
“LoadBehavior”=dword:00000003 to ”LoadBehavior”=dword:00000000
You will need to change the value on all the Office programs individually.  MS Word will be here and so on.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Word\Addins\PDFMaker.OfficeAddin
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Access\Addins\PDFMaker.OfficeAddin
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Excel\Addins\PDFMaker.OfficeAddin
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\MS Project\Addins\PDFMaker.OfficeAddin
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\PowerPoint\Addins\PDFMaker.OfficeAddin
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Publisher\Addins\PDFMaker.OfficeAddin
Now if you have installed one of the Adobe suites that include Contribute, you will see the entry for this plugin also.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\Adobe.Contribute.OfficePlugin
Follow the same steps in all the office keys to prevent it from loading in office also.
