Controlling access to Work at Home rights software

[OverWorked]

I have an MS EES license and I've just set up Office and Windows 7 with e-academy for staff Work At Home rights.

 

There doesn't appear to be any control over who gets to register and download, other than their email domain name.

 

I've only purchased ennough licenses for the staff, and of course WAH doesn't apply to students anyway.

 

How do I stop students (with emails in the same domain) registering on our page at e-academy and downloading MS products and keys?

 

Before I signed up I imagined that all requests had to be approved by me.
