On November 30th, Microsoft released the Internet Explorer VPC testing image. This is a virtual PC image that lets you run IE 6 and IE 7 on the same virtual machine. The image is built on a pre-activated copy of Windows XP SP2 underneath so that could be fun for all kinds of other things too. The catch here is that the image expires on April 1, 2007. Still, it isn't a bad idea to download it and is going to help me make and break IE 6 and 7 stuff a lot faster now. You can download Microsoft Virtual PC 2004 for free to run the image (if you don't have it already). The IEblog states that the VPC image will also run on Microsoft Virtual PC 2007 (download it via connect, Windows Live passport sign-in required) if you're running Vista. Mary Jo Foley, (of Microsoft Watch fame) has written a great article on this over at her new home at ZDNet's "Unblinking Eye on Microsoft" blog that you might find interesting. Be aware, the VPC testing image is around 500MB to download, so go get yourself a cookie, a candy cane, some egg-nog or something while you're waiting.
