Internet Explorer:

In Internet Options, Advanced tab, there is a checkbox that says 'Warn if changing between secure and not secure mode'. Does anyone know of a Registry file that will do the same thing (that is, uncheck that box)? Thanks.

For individual user accounts, or "per-user" installation, use the following subkey:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings

For "per-computer" configurations, use the following subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings

The registry entry WarnOnHTTPSToHTTPRedirect takes the following two values:

• 1: Display the Security Alert message.

• 0: Do not display the Security Alert message.
