In Windows XP Alt-tab keypress sequence to select applications, how can I ensure that certain applications always appear, in a certain order, with others always excluded?

Background for asking is that most XP-based machines that I am working with on a shop floor present the list of shortcuts in a certain order and certain applications.

There is one machine however, that displays an additional application. This is a hindrance to the users of the machines, as the nature of their work is routine and this variation disrupts the remembered sequence, "disrupts their flow".

Thoughts?

Being a good superuser, I research first before asking, and I found:

1. Applications randomly alt-tab? (especially full screen games)

2. Restore Alt-Tab behavior so that minimizing an app once again moves it to the end?

(2. looks close to the control I need, but would need more finer, preciser control over what appears in the selection).

Suggestions? (Thanks in advance.)
