  1. Windows Vista Application Compatibility Simon Martyn Infrastructure Specialist smartyn@iqgroup.net The IQ Business Group Technology Services Division

  2. Agenda • Windows Vista – Innovation and Compatibility • Top Compatibility Issues in Windows Vista • Application Compatibility Toolkit (ACT) 5.0 • Call To Action • Resources • Question and Answer

  3. Innovation and Compatibility Windows Vista Pillars • Security • Reliability • Application Compatibility (most applications just work) • Performance • Feedback and Supportability Improvements in Windows Vista occasionally break compatibility. Microsoft has created these tools and services to help with Application Compatibility • Application Compatibility Toolkit 5.0 (ACT) • Windows Vista Upgrade Advisor 1.0 • Vista Readiness Assessment Tool • Application Compatibility Factory • Windows Logo programs • SWAT team and on campus labs

  4. Agenda • Windows Vista – Innovation and Compatibility • Top Compatibility Issues in Windows Vista • Application Compatibility Toolkit (ACT) 5.0 • Call To Action • Resources • Question and Answer

  5. Top Compatibility Issues With Windows Vista • User Account Control (UAC) • Windows Resource Protection (WRP) • Internet Explorer 7 Protected Mode • Windows Vista 64-bit • Windows Filtering Platform • Deprecations/GINA/Session 0 (High Impact/Low Frequency) • Operating System Version Change • Overall, high compatibility in Windows Vista

  6. User Account Control (UAC) Description • Enabling users to run with a standard user account • Security feature to reduce introduction of vulnerabilities (Malware, Trojan, Viruses) Issues • Custom installers and updaters need administrator privileges • Unnecessary administrator checks • Writing to file or registry locations that are not virtualized Mitigation • Some common shims - Virtualization shims, Force Admin Access • Relax ACL's on files and folders

  7. Windows Resource Protection (WRP) Description • Increase system stability by protecting Windows resources (files, folders, registry). Issues • Application installers that attempt to replace, modify, or delete OS files and/or registry keys that are protected will fail with an access denied error message because the resource could not be updated. Remedies • Never repackage Microsoft redistributables (use the Microsoft provided redistributable package instead). • Do not write to system files and registry keys.

  8. Internet Explorer 7 Protected Mode Description • Internet Explorer 7 runs in Protected Mode, with greatly restricted privileges Issues • IE cannot modify user files, registry keys • Applications may not know how to handle new prompts requesting user permissions Mitigation • Add the site in question to the trusted sites list.

  9. Windows Vista 64-bit Description • Windows Vista fully supports the 64-bit architecture processors from AMD and Intel. • The 64-bit version of Windows Vista can run all 32-bit applications with the help of the WOW64 emulator. Issues • Applications or components that use 16-bit executables, 16-bit installers or 32-bit kernel drivers will either fail to start or will function improperly on a 64-bit edition of Windows Vista. Remedies • Remove all 16-bit components. • Convert 16-bit installers to 32-bit or 64-bit installers • Ensure that all 64-bit drivers are digitally signed

  10. Deprecations Description • Deprecations – removal of APIs or DLLs from Windows Vista that existed in Windows XP Issues • Applications lose functionality or don’t start up correctly Remedies • Search MSDN to look for replacement of API

  11. Graphical Identification and Authentication (GINA) Description • Windows Vista introduces a new authentication model (new Credential Provider API) Issues • Users will not be able to logon using Custom logon applications. These may include: • Biometric devices (fingerprint reader) • Custom UI for logon • Virtual private network (VPN) solutions for remote users with custom logon UI Remedies • The applications or components that use the GINA technology will need to be re-authored to use the new logon authentication model for Windows Vista • For all credential provider information and questions, send e-mail to the Shell Credential Provider alias: credprov@microsoft.com

  12. Session 0 Description • Services are isolated to run in their own private Session (Session 0) to enhance security. • Users no longer share this session Issues • Services with user interaction may hang as UI is not visible to the user Remedies • Update Apps, to ensure services do not display UI • In-box mitigation where notification is sent to current user when there is UI in Session 0

  13. Operating System Version Change Description • The internal version number for Windows Vista is changed to 6. The GetVersion function will now return this version number to applications when queried. Issues • Any application that specifically checks for the OS version will get a higher version number which it may not be designed to handle • Application installers may prevent themselves from installing and applications may prevent themselves from starting. Mitigation • Use compatibility administrator and apply XP SP2 layer or version lie shim

  14. Agenda • Windows Vista – Innovation and Compatibility • Top Compatibility Issues in Windows Vista • Application Compatibility Toolkit (ACT) 5.0 • Call To Action • Resources • Question and Answer

  15. Application Compatibility Toolkit Customer Target • Medium/Large Businesses and Large Enterprises Mission • A lifecycle management tool that assists in identifying and managing your overall application/device/computer portfolio, reducing the cost and time involved in resolving application compatibility issues, and helping you quickly deploy Windows Vista and Windows Updates. Strategy • Help detect, diagnose, and mitigate compatibility issues found in Windows Vista • Microsoft Compatibility Exchange to facilitate exchange of compatibility data between ISV/IHV, Microsoft, and customers • Deliver tools that are timely and relevant to Windows releases
