Have you ever needed to test your web app in multiple versions if Internet Explorer? It is not quite common to have IE6 and IE7 (or IE8) installed on the same computer side by side.
Well, you can still test on both browsers. Microsoft quite conveniently produced a free Virtual PC image for IE6 compatibility testing. Go to Internet Explorer Application Compatibility VPC Image page, where you can download images for IE 6, 7 and 8 Beta 2.
- Internet Explorer 6 on Windows XP SP3
- Internet Explorer 7 on Windows XP SP2
- Internet Explorer 8 Beta 2 on Windows XP SP3
- Internet Explorer 7 on Windows Vista
All you need to run these images is Microsoft Virtual PC. It's all free.
