Query: Windows Registry setting to preventing installation of sponsored product apps (McAfee, etc.)

[Vectrexer2]

To Adobe Support and Others who might know this answer.

What is the Windows Registry Setting a admin could set on a system in order to prevent Adobe products such as Flash, from installing sponsored product applications from installing?

In this case it is  McAfee Security Scan Plus.  However, I also desire to prevent other sponsored apps in the future from being installed during an Adobe product update.  This is a PIA for an admin to follow up on removing an an application from  field systems after was was intended to be an Adobe spcifc product update.

Oracle's JAVA already have a method to disable spnsored installs.  I would like to see the same from Adobe,

Yes I already know to tell people to disable checkboxes for addtional products.

Yes I already know about the direct product dowload links for Flash, etc.

I'm unaware of any such registry mod.
