Not worth installation effort.
They're including a free copy of Windows in that virtual machine. You can use it for 4 months. If they didn't expire it then they'd have to charge for it.
The other options, if you don't have Ultimate, Professional or Enterprise, is to use a licensed copy of Windows in a virtual machine. Then you don't have to be concerned with the expiration.
Microsoft Windows Virtual PC requires processors capable of hardware-assisted virtualization with AMD-V, Intel VT or VIA VT turned on in the BIOS.
I forgot to mention that. On older machines or under-powered, cheaper machines, that's not usually available. You need to have fairly recent hardware for that. Their assumption is that you'll be using Windows 7 on a new machine with new hardware that supports this.
I hadn't heard of that one. I'm a die-hard VMware fan with an MSDN subscription, so I can run any number of Windows installs virtually. IETester is an alpha product and their Bugs & Problems forum has the most posts. That doesn't instill much confidence.
