This release of Windows Script brings the improvements in scripting made during the Vista development cycle to downlevel platforms. The primary reason for changing the version number from 5.6 to 5.7 is to simplify servicing and support by synchronizing the versioning to a consistent scheme based on Vista build number. The minor version increase does not indicate significant new features. The scripting feature set is substantially the same as 5.6, with only minor additions. This is the fastest, most robust, and secure release of Windows Script available.
Improvements have been made with JScript, VBScript & Windows Scripting Host. This release also contains fixes prescribed in various Microsoft KB Articles. For complete details, download the Release Notes for Windows Script 5.7
