From Windows Team Blog:
The shutdown of general availability for the Windows 7 Beta will occur in 3 phases over the course of the next few weeks:
- Starting January 27th, the Windows 7 page will be updated with a warning that time is running out on downloading the Windows 7 Beta and that we will be limiting downloads shortly. People will be encouraged to register and start the download of the Windows 7 Beta sooner rather than later.
- February 10th, new downloads of the Windows 7 Beta will no longer be available. People who have already started their Windows 7 Beta download and have not yet finished will still be able to finish their download and are encouraged to do so.
- February 12th, people will no longer be able to complete their download of the Windows 7 Beta. Anyone who hasn’t finished downloading the Windows 7 Beta will be unable to do so.
