Got this off my mailbox from Windows newsletter, Windows 7 has finally RTMed and it should hit our shelves on 22nd October 2009.

Announcing: Release to Manufacturing
It’s almost here! We’re very happy to tell you that we’ve hit the last big milestone on the way to Windows 7: Release to Manufacturing. We’re packaging copies and manufacturers are putting it on new PCs. On October 22, you’ll be able to get the final shipping product. Pat yourself on the back for a job well done; you helped make this an operating system we’re all going to enjoy.

The Windows 7 RC will be available for download until 20th August 2009. After that, you won’t be able to get the download, but if you have the software, you can still install the RC and get a key if you need one. The keys will be available till March 2010.
