#查看已定义的ConfigurationType
get-command -CommandType Configuration

get-command -CommandType Configuration|Remove-Item （删除）

启用配置：

dsc_service -servicename Spooler（如果没有定义参数的话，则不需要加参数选项）,默认配置文件保存到当前目录下，生成后可以将其移走

将配置推送到目标计算机：

Start-Dscconfiguration -Computername localhost .\dsc_service （由于未在配置中定义目标节点，所以此处使用computername参数作为目标计算机）

-Wait：等待配置完成

-Verbose：输出详细信息流到窗口

查看当前计算机已有的DSC配置（只有start-dscconfiguration之后才能get-dscconfiguration，此处为Message说明）

Get-DscConfiguration

查找DSC可用资源及其相应参数：

Get-DscResource

(Get-DscResource -Name File).properties|ft -Wrap

The Restore-DscConfiguration cmdlet restores the previous configuration for the node, if a previous configuration exists. Specify computers by using Common Information Model (CIM) sessions. If you do not specify a target computer, the cmdlet restores the configuration of the local computer.

$Session = New-CimSession –ComputerName "Server01" –Credential ACCOUNTS\PattiFuller
Restore-DscConfiguration -CimSession $Session
