This is an unelegant "shotgun" approach that I use. Caused no problems but some entries may be superfluous.
From one of reghakr's posts:
----------------------------------
1. To clear forms and passwords information, go to Tools>InternetOptions, click the Content tab, click the AutoComplete button, and choose Clear Forms and Clear Passwords. Uncheck all boxes.
2. In Internet Explorer, go to Tools>Internet Options, click the Advanced tab and uncheck "use inline autocomplete for web addresses" and "use inline autocomplete in Windows Explorer"
3. Backup the registry and/or export the following keys:
go to Start>Run, type regedit. Navigate to:
HKEY_USERS\.DEFAULT\Software\Microsoft\Internet Explorer\IntelliForms\SPW
and delete any encypted entries that are listed in the right pane window.

From somewhere on the web, and from many sources, plus "snapshots of my own registry":
[HKEY_USERS\.Default\Software\Microsoft\Internet Explorer\IntelliForms]
"AskUser"=0
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms]
"AskUser"=0
[HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoComplete]
"AutoSuggest"="no"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoComplete]
"AutoSuggest"="no"
[HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoComplete]
"Append Completion"="no"
"Use AutoComplete"="no"
"AutoSuggest"="no"
Some of these keys will automatically be set when you untick boxes in Tools/Internet Options/Contents/Autocomplete
[HKEY_USERS\.DEFAULT\Software\Microsoft\Internet Explorer\Main]
"Use FormSuggest"= "no"
[HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoComplete]
"AutoSuggest"="no"

Additional changes automatically produced by User select box. I don't mess with them.
