<#
Let's say we want to ensure that a virtual machine has a local user with certain credentials. 
We’ll create a new configuration, located in the file user_configuration.ps1:
#>
configuration Main
{
    param(
        [Parameter(Mandatory=$true)]
        [ValidateNotNullorEmpty()]
        [PSCredential]
        $Credential
    )    
    Node localhost {       
        User LocalUserAccount
        {
            Username = $Credential.UserName
            Password = $Credential
            Disabled = $false
            Ensure = "Present"
            FullName = "Local User Account"
            Description = "Local User Account"
            PasswordNeverExpires = $true
        } 
    }  
} 


#Then, using our handy Azure SDK Powershell cmdlets, we publish our configuration to our Azure storage account:
Publish-AzureVMDscConfiguration-ConfigurationPath.\user_configuration.ps1

<#
Next, we will use an existing virtual machine and set our extension handler and 
desired configuration to apply to it.
#>
$configurationName = "Main"
$configurationArguments = @{ Credential = Get-Credential }
$configurationArchive = "user_configuration.ps1.zip"
$vm = Get-AzureVM "example-1"
 
$vm = Set-AzureVMDSCExtension `
    -VM $vm `
    -ConfigurationArchive $configurationArchive `
    -ConfigurationName $configurationName `
    -ConfigurationArgument $configurationArguments `
 
$vm | Update-AzureVM
