This is the pre-beta developer preview, released Tuesday I think. I have it up and running as of today.
This version is installed on a virtual machine and I can snapshot and restore it anytime I want. I work for a software company and we need to make sure our product works with the new Windows when released, which is my job.
The start menu circle button in Windows 7/Vista functionality sends you too a collection of panels for various programs included in the preview. If you want to get to the command prompt, you need to type "cmd" into a free area on the desktop and then an app menu appears where you can choose it.
I am a supporter of Microsoft software but my first impression is, "what are they thinking?"
I found this site that helped me with the command prompt
