如何向服务器所有用户推送PowerShell弹窗消息？

方法一：直接推送New-WPFMessageBox命令到所有用户会话 #

要将指定的WPF弹窗命令推送给服务器上所有已连接用户，需结合会话管理工具在每个用户的桌面会话中执行命令，步骤如下：

1. 获取所有活跃用户会话
   使用PowerShell获取当前登录用户的会话ID：

   # 获取交互式登录（本地/远程桌面）的用户会话ID
   $sessionIds = Get-CimInstance Win32_LogonSession | 
       Where-Object { $_.LogonType -in 2,10 } | 
       ForEach-Object { (Get-CimAssociatedInstance $_ -ResultClassName Win32_LogonSession).SessionId } |
       Select-Object -Unique
   

2. 在目标会话中执行弹窗命令
   借助psexec工具（需提前安装），在指定会话的STA模式下执行弹窗命令：

   foreach ($id in $sessionIds) {
       psexec.exe -i $id powershell.exe -sta -Command @"
           # 确保New-WPFMessageBox函数已定义（若未全局可用，需在此处粘贴函数代码）
           New-WPFMessageBox -Content `$StackPanel -Title 'Commit ID:$($env:build_sourceversion)' -TitleBackground LightSeaGreen -TitleTextForeground Black -ContentBackground LightSeaGreen
       "@
   }
   

   注意：如果New-WPFMessageBox函数未在目标会话中预先加载，需将函数定义嵌入到执行的命令块中。

方法二：向每个用户会话执行指定脚本 #

你提出的在用户会话中执行指定PowerShell脚本的思路可落地，具体实现如下：

脚本内容（原英文脚本转中文注释） #

Add-Type -AssemblyName PresentationFramework

function New-WPFMessageBox {
    [CmdletBinding()]
    param (
        [Parameter(Mandatory=$true)]
        [System.Windows.UIElement]$Content,
        [string]$Title = "消息弹窗",
        [System.Windows.Media.Brush]$TitleBackground = [System.Windows.Media.Brushes]::DarkBlue,
        [System.Windows.Media.Brush]$TitleTextForeground = [System.Windows.Media.Brushes]::White,
        [System.Windows.Media.Brush]$ContentBackground = [System.Windows.Media.Brushes]::White
    )

    # 创建主窗口
    $window = New-Object System.Windows.Window
    $window.Title = $Title
    $window.WindowStyle = [System.Windows.WindowStyle]::SingleBorderWindow
    $window.SizeToContent = [System.Windows.SizeToContent]::WidthAndHeight
    $window.ResizeMode = [System.Windows.ResizeMode]::NoResize
    $window.Topmost = $true
    $window.WindowStartupLocation = [System.Windows.WindowStartupLocation]::CenterScreen

    # 构建标题栏
    $titleGrid = New-Object System.Windows.Controls.Grid
    $titleGrid.Background = $TitleBackground
    $titleGrid.RowDefinitions.Add((New-Object System.Windows.Controls.RowDefinition -Property @{Height="Auto"}))
    $titleGrid.ColumnDefinitions.Add((New-Object System.Windows.Controls.ColumnDefinition -Property @{Width="*"}))
    $titleGrid.ColumnDefinitions.Add((New-Object System.Windows.Controls.ColumnDefinition -Property @{Width="Auto"}))

    # 添加标题文本
    $titleText = New-Object System.Windows.Controls.TextBlock
    $titleText.Text = $Title
    $titleText.Foreground = $TitleTextForeground
    $titleText.FontSize = 14
    $titleText.FontWeight = "Bold"
    $titleText.Margin = New-Object System.Windows.Thickness(10,5,10,5)
    [System.Windows.Controls.Grid]::SetColumn($titleText, 0)
    $titleGrid.Children.Add($titleText)

    # 添加关闭按钮
    $closeButton = New-Object System.Windows.Controls.Button
    $closeButton.Content = "X"
    $closeButton.Width = 30
    $closeButton.Height = 25
    $closeButton.Margin = New-Object System.Windows.Thickness(5)
    $closeButton.Add_Click({ $window.Close() })
    [System.Windows.Controls.Grid]::SetColumn($closeButton, 1)
    $titleGrid.Children.Add($closeButton)

    # 构建内容容器
    $contentGrid = New-Object System.Windows.Controls.Grid
    $contentGrid.Background = $ContentBackground
    $contentGrid.Margin = New-Object System.Windows.Thickness(10)
    $contentGrid.Children.Add($Content)

    # 组装主布局
    $mainGrid = New-Object System.Windows.Controls.Grid
    $mainGrid.RowDefinitions.Add((New-Object System.Windows.Controls.RowDefinition -Property @{Height="Auto"}))
    $mainGrid.RowDefinitions.Add((New-Object System.Windows.Controls.RowDefinition -Property @{Height="*"}))
    [System.Windows.Controls.Grid]::SetRow($titleGrid, 0)
    [System.Windows.Controls.Grid]::SetRow($contentGrid, 1)
    $mainGrid.Children.Add($titleGrid)
    $mainGrid.Children.Add($contentGrid)

    $window.Content = $mainGrid

    # 显示弹窗并等待关闭
    $window.ShowDialog() | Out-Null
}

# 示例内容面板
$StackPanel = New-Object System.Windows.Controls.StackPanel
$StackPanel.Children.Add((New-Object System.Windows.Controls.TextBlock -Property @{Text="构建已完成！"; FontSize=16; Margin="0,0,0,10"}))
$StackPanel.Children.Add((New-Object System.Windows.Controls.TextBlock -Property @{Text="提交ID: $($env:build_sourceversion)"; FontSize=12}))

# 调用弹窗函数
New-WPFMessageBox -Content $StackPanel -Title "构建完成通知" -TitleBackground LightSeaGreen -TitleTextForeground Black -ContentBackground LightSeaGreen

批量执行脚本到所有用户会话 #

1. 确保脚本文件E:\Script-Popup\Popup-Message - Done.ps1在服务器上所有用户会话均可访问（如放在公共共享目录）
2. 遍历所有用户会话执行脚本：

   # 获取所有活跃用户会话ID
   $sessionIds = quser | Select-Object -Skip 1 | ForEach-Object { ($_ -split '\s+')[2] }
   
   # 在每个会话中执行脚本
   foreach ($id in $sessionIds) {
       psexec.exe -i $id powershell.exe -sta -File "E:\Script-Popup\Popup-Message - Done.ps1"
   }
