As show below, the RUN method of the WSH lets you start a program asynchronously or wait until it terminates depending on the last parameter.
True means wait for the application to end.
It also returns the error code, if any, from the shelled application. The Windows Scripting Host also lets you easily perform basic Registry operations such as reading and writing string or numeric values and deleting single values or entire keys. These operations can be performed on any part of the registry unlike VB's intrinsic SaveSettings and GetSettings commands. However, for more complex operations, such as enumerating values or keys, you will need my Registry. The zip file includes several of Microsoft's sample .VBS files.
