Windows Script Host overview

To run the script, use Microsoft Windows Script Host (WSH), a language-independent scripting host for Windows Script-compatible scripting engines. WSH allows you to run scripts from both the Windows desktop and the command prompt.

To run scripts from Windows, WScript.exe provides a Windows-based dialog box for setting script properties. To run scripts from the command prompt, CScript.exe provides command-line switches for setting script properties.

WSH provides drag-and-drop support for scripts. This means that you can drag files onto a WSH script. The file names are translated into arguments on the command line.

For more information about WSH, see the following resources on MSDN Web site:

• Windows Script Host Basics (https://go.microsoft.com/fwlink/?LinkId=100317)

• Running Your Scripts (https://go.microsoft.com/fwlink/?LinkId=100319)
