When you save a file and you start entering in text in the save dialog box, a drop down list of files that begin with the letters you have typed appear. How do you stop the list from appearing?
The key for this rests in a registry setting.
To stop this behavior, just open your registry editor and goto: HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > AutoComplete
Inside that key are two values that need to be changed: "Append Completion" and "AutoSuggest".
Set both of those to "No" and you should be all set.
if there is no "AutoSuggest" value, just create a new string named "AutoSuggest" and modify the value to "no"
