Excel 2007 : Preventing client Autocompletion of cell data

Can I disable Autocompletion of Cell Data for other users of a specific Excel spreadsheet file?
Explanation: The file is a little vocabulary testing application for language students and, of course, autocompletion would defeat entrirely the object of the test.
I know how to disable Autocomplete on my own computer, but will the disabling of this function carry over with the file so that all other users similarly won't have autocompletion when working with this file?
Is this possible?
Many thanks,
Tarfon

I solved it by acident, myself, I think. Protected sheets don't prompt with Autocomplete scripts from protected data, so that's great. That's all I want! To stop my students being autoprompted with answers in their vocab tests, all I need do is protect the correct answer data columns and I have to do that anyhow to protect my work.
