"Recently we released two images in virtual formats of Windows Vista which will give you a 30 days hands-on experience to play with both a Windows Vista 30-Day Enterprise Edition and Windows Vista with Visual Studio 2005 . Using the power of virtual machines, you can download these Virtual Hard Disks (VHDs) and play with Windows Vista and other apps right away. This means you have minimal set up with no additional hardware required. Once the VHD is downloaded you can test drive right away. All you need is a tool like Virtual PC 2007 which is a new, free product from Microsoft used to set up virtual machines quickly on your desktop. The VHDs are located at www.microsoft.com/vhd. Also stay tuned for more images with both MS products and partner apps.
Check it out and see what you can do with it! Also, to get your hands further into test driving Windows Vista check out Virtual Labs and Windows Vista Test Drive. Both use similar virtualization technologies but work within an online environment. Stay posted for more TechEd 2007 news!"
If you are not sure about Windows Vista this is a great way to try it out.
