需要Powershell cmd来导出本地用户密码有效期

Question

我从Microsoft博客获得了以下powershell脚本。 它完全可以满足我的环境需求，但是它显示密码的有效期为true或false。 我需要提取所有本地用户的确切密码到期日期。 请有人帮助以下脚本获取本地用户帐户的到期日期以及其他信息。

Param
(
[Parameter(Position=0,Mandatory=$false)]
[ValidateNotNullorEmpty()]
[Alias('cn')][String[]]$ComputerName=$Env:COMPUTERNAME,
[Parameter(Position=1,Mandatory=$false)]
[Alias('un')][String[]]$AccountName,
[Parameter(Position=2,Mandatory=$false)]
[Alias('cred')][System.Management.Automation.PsCredential]$Credential
)

$Obj = @()
$now = Get-Date
Foreach($Computer in $ComputerName)
{
If($Credential)
{
    $AllLocalAccounts = Get-WmiObject -Class Win32_UserAccount -Namespace "root\cimv2" `
    -Filter "LocalAccount='$True'" -ComputerName $Computer -Credential $Credential -ErrorAction Stop
}
else
{
    $AllLocalAccounts = Get-WmiObject -Class Win32_UserAccount -Namespace "root\cimv2" `
    -Filter "LocalAccount='$True'" -ComputerName $Computer -ErrorAction Stop
}

Foreach($LocalAccount in $AllLocalAccounts)
{



    $rawPWAge = ([adsi]"WinNT://$computer/$($LocalAccount.Name),user").PasswordAge.Value




    $Object = New-Object -TypeName PSObject

    $Object|Add-Member -MemberType NoteProperty -Name "Name" -Value $LocalAccount.Name
    $Object|Add-Member -MemberType NoteProperty -Name "Full Name" -Value $LocalAccount.FullName
        $Object|Add-Member -MemberType NoteProperty -Name "Disabled" -Value $LocalAccount.Disabled
        $Object|Add-Member -MemberType NoteProperty -Name "Status" -Value $LocalAccount.Status
        $Object|Add-Member -MemberType NoteProperty -Name "LockOut" -Value $LocalAccount.LockOut
    $Object|Add-Member -MemberType NoteProperty -Name "Password Expires" -Value $LocalAccount.PasswordExpires
    $Object|Add-Member -MemberType NoteProperty -Name "Password Required" -Value $LocalAccount.PasswordRequired
    $Object|Add-Member -MemberType NoteProperty -Name "Account Type" -Value $LocalAccount.AccountType
    $Object|Add-Member -MemberType NoteProperty -Name "Domain" -Value $LocalAccount.Domain
    $Object|Add-Member -MemberType NoteProperty -Name "Password Last Set" -Value ($now).AddSeconds(-$rawPWAge)
    $Object|Add-Member -MemberType NoteProperty -Name "Password Age" -Value ($now-($now.AddSeconds(-$rawPWAge))).Days
    $Object|Add-Member -MemberType NoteProperty -Name "Description" -Value $LocalAccount.Description




    $Obj+=$Object
}

If($AccountName)
{
    Foreach($Account in $AccountName)
    {
        $Obj|Where-Object{$_.Name -like "$Account"}
    }
}
else
{
    $Obj
}
}

要获取密码的到期日期，您需要从MaxPasswordAge减去PasswordAge并将结果秒数添加到$now ：

$user = [adsi]"WinNT://$computer/$($LocalAccount.Name),user"
$rawPWAge = $user.PasswordAge.Value
$maxPWAge = $user.MaxPasswordAge.Value
...
$Object | Add-Member -MemberType NoteProperty -Name 'Password Expiry Date' `
                -Value $now.AddSeconds($maxPWAge - $rawPWAge)

---

附带说明，永远不要在循环中使用$Obj+=$Object 。 将对象添加到数组会将所有项目从现有数组复制到新数组（大小+ 1），因此可以确保该操作执行不佳。 最好在管道中使用ForEach-Object循环：

$Obj = $AllLocalAccounts | ForEach-Object {
         $user = ([adsi]"WinNT://$computer/$($_.Name),user")
         $pwAge    = $user.PasswordAge.Value
         $maxPwAge = $user.MaxPasswordAge.Value
         $pwLastSet = $now.AddSeconds(-$pwAge)

         New-Object -TypeName PSObject -Property @{
           'Name'                 = $_.Name
           'Full Name'            = $_.FullName
           'Disabled'             = $_.Disabled
           'Status'               = $_.Status
           'LockOut'              = $_.LockOut
           'Password Expires'     = $_.PasswordExpires
           'Password Required'    = $_.PasswordRequired
           'Account Type'         = $_.AccountType
           'Domain'               = $_.Domain
           'Password Last Set'    = $pwLastSet
           'Password Age'         = ($now - $pwLastSet).Days
           'Password Expiry Date' = $now.AddSeconds($maxPwAge - $pwAge)
           'Description'          = $_.Description
         }
       }

这将自动生成对象列表，然后将其分配给$Obj 。
