While I'm grateful for the VMs I can't fathom the thinking behind the expirations. If I were to actively develop sites that have to work in IE6 I'm forced to re-download the VM ad-infinitum? Better yet, I can't wait till I happen to download it just a day before the expiration and being forced to download it again the next day.

How many sales are you really going to lose because of a free Windows XP VM with IE6 on it? It's ridiculous. 

Thanks for the effort though.
