If you haven’t downloaded the Windows 7 Beta yet, make sure you do so now. The public Beta program will shut down starting on February 10th. Millions of people worldwide have already downloaded and we knew from the beginning that the program would not be unlimited. From tomorrow you will not be able to start new downloads of Windows 7 Beta and from the 12th you can not complete your download. More information about this on the Windows Team Blog. Download the Beta here
If you have a TechNet Subscription you will of course still be able to download the Beta after this date.
