我想我正在为一件非常简单的事情而头晕目眩。我已经研究了两天，不幸的是我无法弄清楚。
问题是我在使用 MDT 部署 Windows 系统时使用了 Powershell 脚本。该脚本在任务序列中最后被调用。在脚本中，我要求重新启动并重试任务，因为应用程序（戴尔更新工具）需要重新启动。
这部分有效，因为在 MDT TS 中它知道它需要重新启动并且还需要重新启动任务。机器重新启动，然后重新运行相同的任务序列，但脚本从未被触发，而 SMSTS.log 确实表示它已成功启动并以代码 0 退出。
然后我注意到退出代码始终为 0，而我在脚本中对此进行了更改。然后我发现我的powershell脚本的返回码有问题，并尝试了以下方法：
测试脚本：
$MyExitCode = 3010
Write-Host ('MyExitcode: [' + $MyExitCode + ']')
Write-Host ('LastExitCode: [' + $LastExitCode + ']')
Write-Host ''
Write-Host 'Setting MyExitCode to LastExitCode'
$LastExitCode = $MyExitCode
Write-Host 'New Result:'
Write-Host ('MyExitcode: [' + $MyExitCode + ']')
Write-Host ('LastExitCode: [' + $LastExitCode + ']')
Read-Host 'Debug Break'
Write-Output $_
Exit $ExitCode
以管理员身份打开 CMD，然后运行以下命令
CMD> powershell.exe -ExecutionPolicy bypass -File "Z:\Applications\Test\TestRerunTask.ps1"
CMD> echo $LastExitCode
CMD> 0
将参数替换为-File将-Command退出代码更改为 1 但仍在 SMSTS.log 中表示它以代码 0 退出
