Good news: default Windows OS disk size is 30 GB from now in Azure
From the beginning I was sad because when I created a Windows Server in Azure the OS disk size was 128GB which generates higher cost and to tell the truth regularly we do not need this huge space on OS disk. And now we could be a little bit happier because from now when you create a Windows Server in Azure the initial OS disk size is “only” 30GB.

Thank you for MS. 🙂
