Holy cow, I wrote a book!
We already saw that
programs in the pin list are pruned from the most-frequently-used
programs list because they would be redundant.
Another fine-tuning rule was introduced after the initial
explorations with the new Windows XP Start menu:
Programs with specific "noise" names are removed from consideration.
Many "noise" programs
were showing up as frequently used because they happened to
be shortcuts to common helper programs like Notepad or Wordpad
to display a "Read Me" document.
These shortcuts needed to be filtered out so that they couldn't be
nominated as, say, the Notepad representative.
The list of English "poison words" is given in
Knowledge Base article 282066.
a program can also register itself as not eligible for inclusion
in the front page of the Start menu by
creating a NoStartPage value
in its application registration.)
We'll see in the epilogue that Windows Vista
uses an improved method for avoiding the
"unwanted representative" problem.
