This is a long standing issue in this group, but I am curious? Is the Screen Saver program to which you refer is the "only" program included that is a demo?
It seems to me that "every" CD sold comes with additional "stuff" to try or not. Any game I buy has limited features (demo) software included. Any application software as well has "extras" which cost "extra". Include as well music and video CD's ...........
No matter what you buy there are options to "upgrade"..... always
One must also remember that Microsoft became the company it did "NOT" through fair practices or clever software.
