Hi there,

The following is taken from http://www.microsoft.com/mscorp/permission/default.mspx

Microsoft Product Icons
Microsoft product icons are the thumbnail-size images indicating that a Microsoft
product has been installed on your operating system. Use of our icons is
permissible in training manuals or documentation written for and/or about
a Microsoft product. In such cases, use of Microsoft icons must be specific
to the function of the icon within the Microsoft software and not used as
a graphical element or design for your own purposes. Further, icons cannot
be modified or altered and must appear as they would within the Microsoft
software.

In addition, Microsoft makes certain icons available for copying and reuse
by others via the terms of the end-user license agreement (EULA) of a software
development tool such as Microsoft Visual Studio or Microsoft Visual Basic.
(Find more information on How to Buy Microsoft Developer Products.) If you
have already licensed a Microsoft development tool such as Visual Studio,
we encourage you to look to the redistributable section of the EULA for more
information about the Microsoft properties that are made available for redistribution
by licensees.

Note: Microsoft does not allow the use of our icons in advertising, in books
and other printed matter, on clothing or other promotional items, in online
and Internet locations, in software applications, in television programs,
commercials, movies, or on videotape, as they are NOT to be used as "artwork"
or design elements.

As I understand it, there are a set of icons that come with Visual Studio
that can be used, but I've heard people say that they arent very good. I
dont know, I've never looked at them.

I know its not a definitive answer but I hope it helps

Kindest Regards
