Microsoft allows you to download  4 VirtualPC images for Internet Application Compatibility

With the Internet Explorer Application Compatibility VPC images, Microsoft is offering developers no less than four free copies of Windows packaged as Virtual Hard Disk Images and designed to integrate with the company's free virtualization offerings. The four VHD downloads feature a new release date, just ahead of the end of 2008, although the launched products are similar to those made available in August 2008, following the availability of Internet Explorer 8 Beta 2.
