Scripting

Hi Folks,

I have a script that I used on Windows Server 2003 and it will work on Windows Server 2008r2.  I use it to run NTBackup.  However, it is not clear to me that WSH will continue to be available.

Should I be moving to "Powershell" and can I write jscript for Powershell?

Should I learn about WMI?  

Thanks for the help,

Chris.
