Vista - Where are settings for "Confirm after download" & "in same window"

What control panel applet or other application dialog can modify these
settings? Registry modifications seem to work, but we wish to include clearly
documented instructions in our manual. For XP we used screen captures of the
Folder Options applet, but these cannot be found in Vista.

We maintain a web application in which Word documents and Excel sheets can be
returned to the user. Both type of Office documents should open in their
associated application window. The scenario we use is to open a pop-up window
that receives either a content type "application/msword" or
"application/vnd.ms-excel". The instructions for the administrators include
the steps to be performed to acquire the systems's functionality, as described
above. (Control Panel -> Folder Options -> DOC or XLS -> Advanced -> clear
check boxes. See also attached picture).

During a conformance test we tested this behaviour on several systems with
most of the possible combinations of Operating System (XP sp2 or Vista),
Office (2000, 2003 or 2007) and Internet Explorer (IE6 or IE7). All systems
behave as reuired, except for both Vista systems (IE7 and Office 2003 or 2007)
where we cannot find where to modify the afformentioned settings.

Some sources suggest that the settings modify two values in the registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.Document.8]
@="Microsoft Word Document"
"EditFlags"=dword:00010000
"BrowserFlags"=dword:00000008
These settings where confirmed using the registry monitor, but on Vista those
changes did not bring the expected result. Using the registry monitor on Vista
while changing the checkbox on the "Always ask before opening this type of
file" dialog that appeares when requesting unknown file types in Internet
Explorer. This revealed that another registry setting was modified:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046}
This is also mentioned in the knowledge base article: 905703. After adding
keys for Word.Document.8 and Excel.Sheet.8 all works as required.
