Windows VM ability to auto-execute customdata
When you pass custom data to a windows virtual machine it gets dropped into a file, but there is no way to have it automatically execute. Linux VMs have this functionality through the linux agent and cloud init. It would be convenient to pass a DSC script or custom startup script through custom data without having to use the CustomScript or DSC extension (because then you don't have to deal with copying files to a storage account or generating SAS tokens).
So this is an old Suggestion - but I'm going to piggy back this.. This is something you can do in EVERY other public cloud. Custom Script Extensions are not comparable to this functionality and it would be trivial to add this into the Image creation process so it's out the box available in Marketplace Skus.
