Azure Virtual Machine OS Disk Size

Hello,

If I create a VM with unmanaged disk, will I be charged for P10 / E10 disk or capacity of the disk I used?

Actually I am looking for an option for OS disk with Windows 10 Pro capacity of 32GB to reduce the cost. Would having a separate storage account and unmanaged disk serve this purpose?

Thanks.

    You will be charged for the "full capacity of 128 GB" (P10/E10 disk), no matter how much data are stored on the disk.

    As far as I know there is no "smalldisk image" available for Windows 10 in the Azure Marketplace.

    There is an option to shrink the OS Disk size after the VM is deployed. But it needs to be done manually:
