提问by Thomas Owens
A Google searchturned up software that performs the same functions as cron, but nothing built into Windows.
一个谷歌搜索变成了软件执行相同功能的cron，但没有内置到Windows。
I'm running Windows XP Professional, but advice for any version of Windows would be potentially helpful to someone.
我正在运行 Windows XP Professional，但是对于任何版本的 Windows 的建议都可能对某人有所帮助。
Is there also a way to invoke this feature (which based on answers is called the Task Scheduler) programatically or via the command line?
是否还有一种方法可以以编程方式或通过命令行调用此功能（基于答案称为任务计划程序）？

For the original question, asking about Windows XP (and Windows 7): Windows Task Scheduler
对于最初的问题，询问 Windows XP（和 Windows 7）：Windows Task Scheduler
For command-line usage, you can schedule with the AT command.
对于命令行使用，您可以使用AT 命令进行调度。
For newer Microsoft OS versions, Windows Server 2012 / Windows 8, look at the schtaskscommand line utility.
If using PowerShell, the Scheduled Tasks Cmdlets in Windows PowerShellare made for scripting.
对于较新的 Microsoft 操作系统版本，Windows Server 2012 / Windows 8，请查看schtasks命令行实用程序。
如果使用 PowerShell，则Windows PowerShell中的计划任务 Cmdlet用于编写脚本。

Use the Windows Task Scheduler to schedule tasks over time and dates.
使用 Windows 任务计划程序按时间和日期安排任务。

The 'at' command.
'at' 命令。
"The AT command schedules commands and programs to run on a computer at a specified time and date. The Schedule service must be running to use the AT command."
“AT 命令调度命令和程序在指定的时间和日期在计算机上运行。调度服务必须正在运行才能使用 AT 命令。”

The closest equivalent are the Windows Scheduled Tasks (Control Panel -> Scheduled Tasks), though they are a far, far cry from cron.
最接近的等效项是 Windows 计划任务（控制面板 -> 计划任务），尽管它们与 cron 相去甚远。
The biggest difference (to me) is that they require a user to be logged into the Windows box, and a user account (with password and all), which makes things a nightmare if your local security policy requires password changes periodically. I also think it is less flexible than cron as far as setting intervals for items to run.
最大的区别（对我而言）是它们需要用户登录到 Windows 框和用户帐户（带有密码和所有内容），如果您的本地安全策略需要定期更改密码，这将使事情成为一场噩梦。我还认为，就设置项目运行的间隔而言，它不如 cron 灵活。
