Thanks for offering these VMs. However, the time limits are quite unfortunate. Wouldn't it make far more sense to create crippled versions of Windows that only can run IE that don't even have things installed necessary to run anything else with no time limits? It would kill the overhead necessary to run a full version of Windows for each version as people typically need to have multiple versions open at a time for testing purposes. It would eliminate the need for these silly time limits, too.
