How to remove an autocomplete option from notepad++

I am using notepad++ and have enabled the autocomplete feature. For the most part I like having it, but there are a few words it tries to autocomplete that just interfere with my productivity.

For example, whenever I try to type <?php it will attempt to autocomplete to <?php_egg_logo_guid, <?php_init_loaded_file or a sundry of other such options. It is a bit annoying and I don't even know what the use of any of them are.

I would like to remove these unneeded options from autocomplete. Is it possible? If so, how?

Thanks!

Edit: After a few bad answers, let me clarify: I am not trying to disable autocomplete completely, just remove a word or two from the dictionary of choices which it chooses to give hints from.

Edit the relevant .xml in notepad++'s program files's plugins\APIs to remove the silly php autocompletes as explained here.
