What is the MSDN Volume License Registration site and who needs to register their licenses?
The MSDN Volume License Registration site is for Open, Select, and Enterprise Agreement customers. Customers who register their licenses will receive access to MSDN Subscriber Downloads, technical support, and an MSDN Subscriber ID. Customers who ordered their licenses through the Software Assurance program may also receive complimentary media, based on number of licensees ordered. All customers who register at the site will need to establish a unique Passport. The registration site will prompt all customers to enter their Passport. Customers who already have a Passport may use their current Passport. Customers who do not have a Passport will be prompted to create one. Please visit the Microsoft Passport Network for more information about Passport.
