Icons licence in Vize Posted November 9, 2009 Most of those replacement icons are actually made by Microsoft but already used elsewhere in their products. Some other icons, including the Vize program icon, were done by other people. XPero sorted out the arrangements for those icons and I don't have any of his records relating to the original authors so I can't help you out here.Do note that Microsoft prohibits use of their icons and other pieces of artwork as design elements in things like website designs though they are allowed for appropriate use in an application (desktop or web) such as for toolbar buttons. To that end, I think the xpze and Vize websites are really pushing the limit on what you can do with MS's official icons and wallpaper artwork.If this is for an internal application, I don't think Microsoft really cares. I've got many contacts at Microsoft, including many at rather senior positions and they all seem to have a live-and-let-live attitude as regards this stuff, MS Legal only gets involved if it's serious, and this is not serious . BTW Visual Studio (since 2005) comes with a massive icon and toolbar art library for this exact purpose.
