Why do I have to install program to learn more about it?

TR has made a huge change to its presentation of new programs. Instead of clicking on a learn more or read more hot spot and getting a pdf file showing me more information about a program, I get a program I have to install. There is no choice to learn some details of the program without installing a program. Constantly installing and uninstalling programs is what leads to slow computers over the years. This is due in part because uninstalling these programs is often incomplete leaving dlls and registry entries in place after the program is supposedly removed.
