Explanation:
The Microsoft® Application Compatibility Toolkit (ACT) 5.6 enables software developers, independent software vendors (ISVs), and IT professionals who work in a corporate environment to determine, before deployment within the organization, whether their applications are compatible with a new version of the Windows® operating system. ACT also enables such individuals to determine how an update to the new version will affect their applications.
You can use the ACT features to:
Verify your application's, device's, and computer's compatibility with a new version of the Windows

operating system, including determining your risk assessment.
Verify a Windows update's compatibility, including determining your risk assessment.

Become involved in the ACT Community, including sharing your application assessment with other ACT

users.
Test your applications for issues related to User Account Control (UAC) by using the Standard User

Analyzer (SUA) tool.
Test your Web applications and Web sites for compatibility with new releases and security updates to

Internet Explorer®, by using the Internet Explorer Compatibility Test Tool.
