Do you do web development and are unable to test your software in old shitty versions of Internet Explorer?
If so then you may want to read on a little bit.
Microsoft has got a whole bunch of virtual images you can download for FREE(not a usual Microsoft word) over here:

They contain an operating system and an install of your favourite IE version! Hooray!
They have IE6 on XP SP3, IE7 on Vista, IE8 on XP and Vista.
You are supposed to install/run the virtual disc image under Microsoft’s very own Virtual PC, but you could always take a look at Sun Microsystems’ VirtualBox which is 100% FREE and in my opinion a better choice between the two virtual machines.
