If you make the product key available in the user-data attribute, you
can extract it via the scripting language of your choice from
http://169.254.19.254/latest/user-data and then install the key:

  slmgr /ipk <product_key>

And then activate windows:

  slmgr /ato

If the product key is the *only* thing in your user-data attribute,
you can do something like this with PowerShell:

  $web = new-object system.net.webclient
  $data = $web.DownloadString("http://169.254.169.254/latest/user-data")
  slmgr /ipk $data
  slmgr /ato
