Deprovision Azure VM from guest
Azure has two types of VM resources (amongst other things). Classic and ARM (Azure Resource Manager). Classic, as the name implies, is the older version of the infrastructure which uses cloud services. ARM is the new version and if you just created a VM from the portal with teh defaults this is what you will have got.
To de-allocate that VM so your not charged then you should use the Stop-AzureRMVM command, this requires the name of the VM and the resource group it is in, you should be able to see this from the portal.
Stop-AzureRmVM -ResourceGroupName "ResourceGroup11" -Name "VirtualMachine07"
