Question

我有一个登录脚本，如果启动PC的时间超过允许的时间，它将重新启动PC。

我有一个PowerShell脚本，该脚本在登录期间运行，每周执行一次，以检查计算机的正常运行时间，如果> 48小时，则重新启动。该脚本允许用户请求扩展名，这样就不会立即将其踢出计算机。我有1、3、8小时的延长时间。只有1、3小时的延期工作。看来，如果您输入一个大于3的值，它将不接受它。有没有办法使此“扩展”工作时间超过3小时？

~~这是shutdown.exe可执行文件的限制。根据此处找到的文档：~~

https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/shutdown

/t <XXX> Sets the time-out period or delay to XXX seconds before a restart or shutdown. This causes a warning to display on the local console. You can specify 0-600 seconds. If you do not use /t, the time-out period is 30 seconds by default.

如果要超出此范围，则必须在PowerShell中创建暂停，然后再执行shutdown.exe。这可以通过在8小时选项中添加start-sleep，休眠3小时然后指定最多600秒的计时器来完成。

编辑：：该文档似乎已过时，并且关闭可以接受长达10年的任何内容（以秒为单位）。看，shutdown命令只需要几秒钟。您应该能够仅用秒x分钟x小时来计算，而不是您要尝试的所有奇特数学。一分钟60秒，一小时60分钟，因此唯一改变的是延迟的小时数。试试这个：

$Global:hash.ScheduleBtn.Add_Click( {

    $startTime = switch ($Global:hash.ScheduleValue.SelectedItem.Name) { 
        "one" { 1*60*60 } 
        "three" { 3*60*60 } 
        "eight" { 8*60*60}
    }
    $Global:hash.Timer.Stop()

    cmd.exe /c shutdown.exe -r -d P:0:0 -t $startTime -f 

    $Global:hash.Window.Close()
}
