Microsoft Trivia: What MS products do these icons represent? (+ scavenger hunt!)

http://img231.imageshack.us/my.php?image=requestedgraphicsns9.png

That link points to an image containing four low-res versions of Microsoft icons. The last two icons are for Office 2007 and Windows Vista. What products do the first two icons represent?

And does anyone know where I could find some high-res versions of the first two pictures (i.e., an online MS image gallery)? Double-points if you can actually find the high-res pictures for me!

This is for work, btw, so I/we would really appreciate your help!

Edit: Sorry about using Filedropper. I’m using imageshack now.
