Inclusion list for moderate risk file types

This policy setting allows you to configure the list of moderate-risk file types. If the attachment is in the list of moderate-risk file types and is from the restricted or Internet zone, Windows prompts the user before accessing the file. This inclusion list overrides the list of potentially high-risk file types built into Windows and it takes precedence over the low-risk inclusion list but has a lower precedence than the high-risk inclusion list (where an extension is listed in more than one inclusion list).

If you enable this policy setting, you can specify file types which pose a moderate risk.

If you disable this policy setting, Windows uses its default trust logic.

If you do not configure this policy setting, Windows uses its default trust logic.

Supported on: At least Windows XP Professional with SP2

Specify moderate risk extensions (include a leading period, e.g. .doc;.pdf;).
