As much as I understand what you're saying in here (and I'm not defending Microsoft, because it's not my favourite tech company), would you expect them giving courses about J2EE and how to use Erlang?
I can say I was at least a little surprised they didn't have anything for node.js, considering how much they're starting to use it internally, and how much they've invested into getting node.js working as a first class citizen in Windows.
I don't know about Erlang, but a lot of J2EE deployments are on Windows servers. It would make some sense even if the goal was to sell Windows servers.
You're right about deployments of J2EE on Windows servers, my point here was that they might have guides on how to tie some knots together to make Java <> Windows play nicely, but I wouldn't expect too much. After all, Microsofts target is providing you with full solution to your business needs.
They need to start giving free guides, giving software (BizSpark) might not be enough if people don't know how to use it. And as much as I dislike some of the policies which Microsoft has, I would be lying when telling, that I didn't found pleasure while working with tools like SQLServer or the.
Also, as tracker1 said below - I'm also surprised with node. They know that getting some other languages (ruby, python) to work on Windows can be a bit "hard", especially in production deployments (try using some tools written in ruby, like veewee + vagrant + virtualbox combo), you would expect that they would at least advertise nodejs more.
