1. The article [Q217148] describes how to use the Autocomplete feature turned on by default for Web addresses and commands or folder names in IE, and the functionality of this feature.
2. The PCMagazine article (second page) [AutoWhat? 2] explains that each input field in a Web-based form has an internal name that identifies the field to the system, and under Windows 9x (95/98/Me), the internal field names are visible in the Registry, but the data is encrypted. Under Windows NT (NT 4.0/2000/XP), even the field names are inaccessible.
Note: The PC Magazine Utility Library is now available by subscription only.

3. Features or options which may be applied is located in the Main menu of IE by clicking Tools, Internet Options, Advanced tab:
a. Use inline AutoComplete for Web addresses - specifies whether to complete entries when a Web addresses is typed in the Address bar based on entries used previously.
b. Use inline AutoComplete in Windows Explorer - specifies whether to complete entries when typing file names, paths, or folders in the Address bar or Run dialog box based on entries previously used. For example, when typing E:\Public\project1\t, in the Address bar, AutoComplete will probably suggest "E:\Public\project1\templates."
Note: Something to consider if anomalies are still present when using the Autocomplete functions is whether corruption exists in any of the following areas. For all versions of IE except Windows Millennium and I don't know why not, the article [Q160158] describes two methods of behavior which can occur if files in the Temporary Internet Files and History folders, to include the Index.dat file they contain, which may become corrupted and how to deal with the situation for MSN, but regardless of whether the IE version used is the MSN or not, it still applies.
(1) The Address toolbar in IE, Windows Explorer, or on the Windows desktop or taskbar
(2) The Open box in the Run dialog box accessed from the Start menu, or the Open dialog box accessed from the File menu in IE
(3) Forms (including user names and passwords on forms) on Web pages
