  1. CN1260 Client Operating System Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+

  2. Agenda • Chapter 9: Dealing with Software Issues • Quiz • Exercise

  3. Software Program • A sequence of instructions written to perform a specified task for a computer • Execute an executable file; .exe or .msi, to install the program

  4. Managing Programs • Use the Control Panel’s Programs and Features to • Uninstall programs • Change a program’s configuration by adding or removing certain options • Some program allows you to repair • To change the program, click Change or Repair • Administrator privilege is required sometime • See Figure 9-1 on Page 174

  5. Program Compatibility • Program Compatibility Troubleshooter • A wizard that simplifies the process of selecting compatibility mode settings for an executable file • Change compatibility settings manually • Right-click the program icon-> Properties -> Compatibility tab • See Figure 9-2 on Page 176 • To suppress application compatibility warnings • Computer Configuration\Administrative Templates\System\Troubleshooting and Diagnostics\Application Compatibility Diagnostics

  6. Application Compatibility Toolkit (ACT) • To be used to determine before software deployment whether the software is compatible with Windows 7 • The tools included in the kit are as follows: • Application Compatibility Manager • Compatibility Administrator • Internet Explorer Compatibility Test Tool • Setup Analysis Tool • Standard User Analyzer

  7. Application Compatibility Manager • Designed for large-scale Windows 7 deployments • Collect • To collect information from other computers on the network, you create data collection packages (DCPs) • Analyze • The analysis of the collected data begins with organization, which can include categorization, prioritization, application assessment, and assignment of deployment status • Test and Mitigate • Test applications and create mitigation strategies, using the Compatibility Administrator application

  8. Compatibility Administrator • A main area for solutions to known compatibility problems for hundreds of commercial Windows 7 applications

  9. Software Shim • A compatibility fix that consists of a small library that transparently intercepts certain application calls and changes the parameters passed, handles the operation itself, or redirects the operation elsewhere so that the application will operate properly • It is usually used for older applications that rely on older functionality that may have been altered for Windows 7

  10. Internet Explorer Compatibility Test Tool • Examines the compatibility of the web sites and web-based applications in real time with Windows Internet Explorer 7 and 8

  11. Setup Analysis Tool • Logging tool to analyze application setup programs for compatibility issues • Installation of 16-bit components • Installation of Graphical Identification and Authentication DLLs • Changes to files or registry keys that exist under Windows Resource Protection

  12. Standard User Analyzer • Examines applications for compatibility issues caused by the User Account Control (UAC) feature of Windows 7 • The stand-alone version of SAT can monitor any Windows and third-party installers • The Virtual SAT tool can only monitor Windows and third-party installers that run unattended

  13. Windows XP Mode • Creates a virtual machine running Windows XP on your Windows 7 system • Require Windows 7 Professional, Enterprise, or Ultimate editions • Used for applications that will not run any other way • Has extensive hardware requirements

  14. Configuring Application Restrictions • Restricting the applications that users can run on their computers • Two mechanisms for restricting application • Group Policy settings: software restriction policies • Computer Configuration\Windows Settings\Security Settings\Software Restriction Policies • Right-click the Software Restriction Polices object -> Create Software Restriction Policies • See Figure 9-3 on Page 182 • AppLocker

  15. Using Software Restriction Policies • Certificate rules • Based on the inclusion of a certificate signed by the software publisher • Hash rules • Based on a digital fingerprint that remains valid even when the name or location of the executable file changes • Network zone rules • Identify Windows Installer (.msi) packages downloaded with Internet Explorer based on the security zone of the site from which they are downloaded • Path rules • Identify applications by specifying a file or folder name or a registry key • Default rule • Applies when an application does not match any of the other rules

  16. Configuring Rule Settings • The three possible settings • Disallow • Basic User • Unrestricted • Resolving Conflicts • The more specific rule takes precedence over the less specific. • Hash rules • Certificate rules • Path rules • Zone rules

  17. Using AppLocker • Application Control Policies • New feature in Windows 7 Enterprise and Ultimate • Creation of rules is easier than Group Policy • Wizard-based • Only applies to Windows 7 and Windows Server 2008 R2

  18. Understanding Rule Types • Rule Types • Executable rules • Contains rules that apply to files with .exe and .com extensions • Windows Installer rules • Contains rules that apply to Windows Installer packages with .msi and .msp extensions • Script rules • Contains rules that apply to script files with .ps1, .bat, .cmd, .vbs, and .js extensions • Criteria for resource access: • Publisher • Path • File Hash

  19. Troubleshooting Applications • As with any problem, you should first identify the problem and determine its scope • Does the problem occur on one computer only or does it involve multiple computers • Determine if it is a local application, a network application or a local application that requires network access to fulfill its task • If the application worked before, you then need to ask if anything has changed • Check the Event Viewer • Verify the configuration of the software. • Try to research the problem on the Internet or with the vendor

  20. Assignment • Submit these before class over on Thursday • Fill in the blank • Multiple Choice • True / False • Submit these before class start on Monday • Lab 9 • Case Scenario 9-1
