Microsoft responds to Windows 7 student upgrade SNAFU with direct ISO download
Thanks to Phil for the update!
Also, don't bother downloading this ISO if you don't have a valid student-only product key. You'll probably be able to install it, but your key won't activate the OS.
Your product key MUST MATCH the version you install. A Pro key will not activate a Home Premium install.
Once you download the disc, just open the ISO with your favorite burning software and burn it to a DVD - or drop it on a 4GB or larger USB drive using Microsoft's free utility.
