Hi Anuj
One possible way to do this is to use the Microsoft Script Control. From TestStand, use the ActiveX/COM Adapter with an Action step type. Right-click on the step and select "Specify Module...". In the automation field, you can select "Microsoft Script Control 1.0". There should also be a help file for this program located in C:\WINDOWS\SYSTEM32\MSSCRIPT.HLP that should help get you started.
