需要 powershell cmd 导出本地用户密码到期日期

Question

我从 Microsoft 博客获得了以下 powershell 脚本。它完全满足我的环境需求，但它将密码到期日期显示为真或假。我需要提取所有本地用户的确切密码到期日期。请有人帮助使用以下脚本来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
}
}

要获得密码到期日期，您需要从MaxPasswordAge 中减去PasswordAge，然后将得到的秒数加上$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，您永远不应该在循环中使用$Obj+=$Object。将对象添加到数组中会将现有数组中的所有项复制到新数组（大小 + 1），因此保证操作执行不佳。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
         }
       }

这将自动生成一个对象列表，然后将其分配给$Obj。
