Oh, man! One of those well kept secrets! If nobody tells you how it is not as easy as one might seem. I would have expected Microsoft to send out a bunch of keys in my welcome pack, but that sadly enough was not the case. So how do we get those vpc images running before the class starts?
The trick is knowing whom to ask. You would have expected to have this as part of the MCT FAQ but no, no info there. There used to be a link on the MCT homepage, but no luck there either.
After spending ages going through the MCT homepage I gave up looking for the link. It is gone.
This is how you do it:
Send an Email to "mslpkd" at microsoft with your request for product keys and your MCT ID (also known as MCP ID). They will then send you back a nice email with instructions and some time later another email with the keys you requested. You can request keys for Windows 2003, XP, SBS, and Vista. Then follow the instructions to change the product key of the vpc images during the activation process and activate the vpc by phone.
Remember to commit changes to the VPC after doing that and reusing that activated image for your class. You really don't want to go through the hassle of activating each and every image for a class of eight people every other week! At some point in stage you will have maxed out the amount of activatons you can do with those keys and simply send another email to the same address aksing for some more.
It really isn't that hard, when somebody tells you how to do it!
