The TechNet page that briefly provided links to the public beta release of Windows 7 before "server too busy" errors took the site down finally returned, but not until, well, just about everybody began circulating direct links to Windows 7 downloads. Unfortunately, these direct links no longer work, and the public beta program has now ended. However, if you're a TechNet or MSDN subscriber, you can still download the beta via this link. If your download was interrupted, you can still finish it. And, you can still register for a product key or look up the key you’ve already gotten.
