I ‘ve received a message from Microsoft telling that MS is retiring the Technet program:
Microsoft is retiring the TechNet Subscriptions service to focus on growing its free offerings, including evaluation resources through the TechNet Evaluation Center, expert-led learning through the Microsoft Virtual Academy, and community-moderated technical support through the TechNet Forums to better meet the needs of the growing IT professional community.
The last day to purchase a TechNet Subscription through the TechNet Subscriptions website is August 31, 2013. Subscribers may activate purchased subscriptions through September 30, 2013.
Microsoft will continue to honor all existing TechNet Subscriptions. Subscribers with active accounts may continue to access program benefits until their current subscription period concludes.
Although Microsoft offers some alternatives, I pretty liked the TechNet subscription program. As a member you have access to most of Microsoft’s infrastructure software (Windows Server, Exchange, SQL, etc.) including the required license keys. Although you’re not allowed to use TechNet keys in a live production environment, performance testing, usability and comparison of features is all allowed which makes TechNet ideal for lab usage.
You can still buy a Technet subscription until August 31, 2013 (which will be valid for one year). After that you have to look for an alternative, for example MSDN or use the free product evaluation options which is available in most Microsoft products.
