1.) Only students taking at least one for-credit course in a department with an MSDN-AA agreement may download/install available software.
2.) The software may only be used for educational/instructional and research purposes; you cannot use it for generic personal use, nor for commercial use. Windows, specifically, may only be installed in order for you to run other MSDN-AA software.
3.) The license remains valid for life, even after the licensing agreement with Microsoft expires, you complete the course, etc. However, you must continue to follow the conditions in #2, and you are not entitled to future downloads, version updates (ex: Windows 7 to Windows
, etc. once your access to MSDN-AA is terminated, for whatever reason.
4.) It is not a basis for purchasing future Upgrade licenses.
Aside from the licensing differences, essentially restricting to use for departmental course work, it is exactly the same as the retail version, with the DVDs being interchangeable.
Hope this helps,
