【问题描述】：
我有一个 powershell 脚本，它可以在工作站上本地运行或使用 PSEXEC 工具远程运行，它会显示一个对话框来控制台用户 PC 将在 X 时间和计时器内重新启动。对话框不能关闭，只能最小化（这是按照代码）。但是，当我运行它时，它还会在对话框的后面显示 Powershell 屏幕，关闭它也会关闭表单。
我尝试了 Powershell 开关 [-NoLogo]、[-NonInteractive]、[-WindowStyle Hidden]，它不起作用。
这是自定义重启脚本：
Function Create-GetSchedTime {
Param(
$SchedTime
)
$script:StartTime = (Get-Date).AddSeconds($TotalTime)
$RestartDate = ((get-date).AddSeconds($TotalTime)).AddMinutes(-5)
$RDate = (Get-Date $RestartDate -f 'dd.MM.yyyy') -replace "\.","/" # 16/03/2016
$RTime = Get-Date $RestartDate -f 'HH:mm' # 09:31
#&schtasks /delete /tn "Post Maintenance Restart" /f
#&schtasks /create /sc once /tn "Post Maintenance Restart" /tr "'C:\Windows\system32\cmd.exe' /c shutdown -r -f -t 300" /SD $RDate /ST $RTime /f

你也试过
-WindowStyle Minimized吗？ -
似乎与 this 重复。
-
还考虑使用 PS2EXE 来处理这种事情——它将你的脚本编译成可执行文件，并有一个专门用于隐藏 PS 窗口的开关。 gallery.technet.microsoft.com/scriptcenter/…

谢谢，当我在 Powershell 之后放置“-WindowStyle Hidden”开关时，它起作用了。感谢你的回复。 @DevX，实际上我正在尝试做相反的事情。
-
谢谢@Sceptalist，会检查的。
