Question

我想通过删除最近6个月内未登录服务器的C：\用户的用户配置文件来释放服务器上的C盘空间。我使用PowerShell Cim命令连接到服务器。

到目前为止，我只发现了Get-CimInstance -CimSession $CimSession -ClassName Win32_UserProfile命令，该命令将列出用户个人资料，但没有列出每个用户的上次登录时间。是否有另一个命令可用于使用LastLogon列出UserProfiles？有了该列表后，我想删除最近6个月内未登录服务器的所有配置文件。

How to delete user profiles older than a specified number of days in Windows

此PowerShell脚本示例显示如何删除早于指定天数的用户配置文件。

Example 1:  

C:\Script\RemoveLocalUserProfile.ps1 -ListUnusedDay 1

Example 2: 
C:\Script\RemoveLocalUserProfile.ps1 -DeleteUnusedDay 1 -ExcludedUsers “marry” 

# Begin Script
If ($ProfileInfo -eq $null) 
{ 
    Write-Warning -Message "The item not found." 
} 
Else 
{ 
    Foreach ($RemoveProfile in $ProfileInfo) 
    { 
        #Prompt message 
        $Caption = "Remove Profile" 
        $Message = "Are you sure you want to remove profile '$($RemoveProfile.LocalPath)'?" 
        $Choices = [System.Management.Automation.Host.ChoiceDescription[]]` 
        @("&Yes", "&No") 

        [Int]$DefaultChoice = 1 

        $ChoiceRTN = $Host.UI.PromptForChoice($Caption, $Message, $Choices, $DefaultChoice) 

        Switch ($ChoiceRTN) 
        { 
            0
            { 
                Try {$RemoveProfile.Delete(); Write-Host "Delete profile '$($RemoveProfile.LocalPath)' successfully."} 
                Catch {Write-Host "Delete profile failed." -ForegroundColor Red} 
            } 
            1 {break} 
        } 
    } 
    $ProfileInfo|Select-Object @{Expression = {$_.__SERVER}; Label = "ComputerName"}, ` 
    @{Expression = {$_.ConvertToDateTime($_.LastUseTime)}; Label = "LastUseTime"},` 
    @{Name = "Action"; Expression = {If (Test-Path -Path $_.LocalPath) 
            {"Not Deleted"} 
            Else 
            {"Deleted"} 
        }
    } 
}
# End Script

Answer 2

删除个人资料时请多加注意，您不想访问计算机专用帐户。 Win32_UserProfile类具有您可以依赖的LastUseTime属性。

$session = New-CimSession -ComputerName $cn
$gcimParams = @{
    'CimSession' = $session
    'ClassName'  = 'Win32_UserProfile'
    'Filter'     = 'RefCount<1 and Special="false" and Loaded="false"'
}
$profileList = (Get-CimInstance @gcimParams).Where{$PSItem.LastUseTime -lt (Get-Date).AddMonths(-6)}

foreach ($user in $profileList)
{
    $user | Remove-CimInstance -CimSession $session
}
