Auto logon(1)：Create auto logon with WMI by using Power Shell Script

Step1、將以下的指令寫入文字編輯器，並存成"autologon.ps1

######宣告變數，$computer也可以為$computer="localhost

param (

  [Parameter(Mandatory=$false)][String[]]$computer = ".",

  [Parameter(Mandatory=$false)][String[]]$computerName = $env:computername,

  [Parameter(Mandatory=$false)][String]$DefaultDomainName = $env:USERDOMAIN,

  [Parameter(Mandatory=$false)][String]$DefaultUserName = "test",

  [Parameter(Mandatory=$false)][String]$DefaultPassword  = "pwd",

  [Parameter(Mandatory=$false)][String]$Group  = "administrators",

  [Parameter(Mandatory=$false)][Int]$AutoLogonCount

)

######使用net use建立新user account

function create_user_netuser(){

net user /add $DefaultUserName $DefaultPassword   ######建立新user account

net localgroup $Group $DefaultUserName /add  ######分配administrator的權限給新user account

}

######使用ADSI (Active Directory Service Interfaces)建立新user account

function create_user_ADSI(){

    ######建立新user account

$objou=[ADSI]"WinNT://$computerName,computer"

$objuser=$objou.Create("user", $DefaultUserName)

$objuser.SetInfo()

$objuser.SetPassword($DefaultPassword)

######分配administrator的權限給新user account

$objou=[ADSI]("WinNT://$computerName/$Group,group")

$objou.add("WinNT://$DefaultUserName,user")

}

######修改registry來enable auto logon

function add_autologon(){

 foreach($computer in $computerName){ 

      #do local modifications here

      Write-Verbose "Adding required registry values on $($computer)"

      Write-Verbose "Saving curent location"

      Push-Location

      Set-Location "HKLM:\Software\Microsoft\Windows NT\Currentversion\WinLogon"

      New-ItemProperty -Path $pwd.Path -Name "AutoAdminLogon" -Value 1 -PropertyType "String" -Force | Out-Null

      New-ItemProperty -Path $pwd.Path -Name "DefaultUserName" -Value $DefaultUserName -PropertyType "String" -Force | Out-Null

      New-ItemProperty -Path $pwd.Path -Name "DefaultPassword" -Value $DefaultPassword -PropertyType "String" -Force | Out-Null

      New-ItemProperty -Path $pwd.Path -Name "DefaultDomainName" -Value $DefaultDomainName -PropertyType "String" -Force | Out-Null

      if ($AutoLogonCount) {

        New-ItemProperty -Path $pwd.Path -Name "AutoLogonCount" -Value $AutoLogonCount -PropertyType "Dword" -Force | Out-Null

      }

      Write-Verbose "restoring earlier location"
