I want to use Windows Task Scheduler to execute my ASP.NET web page (.aspx). I read that Windows Powershell can help in this. The post [asp.net script in task scheduler](https://stackoverflow.com/questions/4559978/asp-net-script-in-task-scheduler)

tells a command "powershell.exe -c (new-object system.net.webclient).downloadstring('<http://localhost/myscript.aspx>')"
to execute .aspx page. But I'm unable to add this line into Windows Task Scheduler, (I'm using Windows XP)
