Complete Internet Explorer collection on a single computer

You know how difficult is to test a web site on the many (conflicting) versions of Internet Explorer browsers that were created. While most of us don't even bother to test for anything lower than IE 6.0, there are major differences between IE6, 7 and 8. I used to use something called MultipleIEs before that contained IE versions up to 6, but now I found something that looks even better: IE Collection, boasting IE versions up to and including Internet Explorer 8.0.

I have installed it and so far I had no major issues with it. It does seem to change some part of the default IE configuration, so take a look there after you finish installing it.
