Lesson 2: Configuring and Troubleshooting Windows Aero 143 Lesson Summary ■ Before you try to troubleshoot Aero, make sure that the edition of Windows Vista that you are using supports it. ■ To support Aero, a graphics adapter must be DirectX 9 capable, have a WDDM driver, have Hardware Pixel Shader 0 support, support 32-bit color, and have at least 64 MB of graphics memory. ■ You can check whether Aero is running by pressing both the Windows and the Tab key at the same time. ■ Setting Windows to use 16-bit color disables Aero. ■ Windows Genuine Advantage checks allow you to download extra applications and operating system components if you have a genuine copy of Windows. ■ The WGA check does not send your personal information to Microsoft. ■ If your computer fails a WGA check, you will be able to download from Windows Update only updates that are rated as critical by Microsoft. Updates that are rated as important or moderate will not be available through Windows Update. ■ The System Performance Rating tool generates the Windows Experience Index number by evaluating a computer’s processor, RAM, graphics adapter, and hard disk drive per- formance. The Index rating is the lowest number of all of these components. Lesson Review You can use the following questions to test your knowledge of the information in Lesson 2, “Configuring and Troubleshooting Windows Aero.” The questions are also available on the companion CD if you prefer to review them in electronic form.

Key Terms Do you know what these key terms mean? You can check your answers by looking up the terms in the glossary at the end of the book. ■ flicker ■ legacy hardware device ■ plug and play ■ Power Management ■ refresh rate ■ resolution ■ resources Chapter 3 Review 147 Case Scenarios In the following case scenarios, you will apply what you have learned about troubleshooting post-installation configuration issues and troubleshooting Windows Aero. You can find answers to these questions in the “Answers” section at the end of this book. Case Scenario 1: Post-Installation Troubleshooting You are preparing 10 Windows Vista computers that will be used as workstations in an Ant- arctic research outpost. You need to ensure that all hardware and software works correctly before shipping the computers to the South Pole. When configuring the computers, you have come up against the following problems: 1. One type of legacy device, installed in five of the Windows Vista computers, does not appear in the Device Manager. What steps should you take to install it? 2. On three of the computers there is a conflict between two scientific devices. What method could you take to resolve this conflict? 3. One special device conflicts with COM1. You are unable to modify the resources used by either the device or the COM port. What course of action could you take to ensure that the device works? Case Scenario 2: Troubleshooting Aero and Display Settings You are developing guidelines for a group of postgraduates who share several Windows Vista computers in a lab. You want to give them information so that they know the effect that mak- ing changes to display settings and themes has on other users. As a part of this process, you need to answer the following questions: 1. Under what conditions could a user with standard privileges accidentally disable Aero for all the others? 2. One student gets headaches because she perceives the monitor to be flickering. What is a possible drawback to increasing the refresh rate? 3. One student has visual difficulties and needs the monitor set to a low resolution. Will this affect the other students? Suggested Practices To help you successfully master the exam objectives presented in this chapter, complete the following tasks. 148 Chapter 3 Review Troubleshoot Post-Installation Configuration Issues ■ Practice 1: Maximum Refresh Rates for Each Resolution If you have a CRT monitor, make a table for the maximum possible refresh rate for each resolution that your graphics adapter and monitor is capable of displaying. Alter the refresh rate of your CRT monitor at your preferred resolution. See if you can notice the difference. You might have to manually adjust your monitor’s horizontal and vertical settings. ■ Practice 2: Alter Hardware Settings Using Device Manager Use hardware manager to alter the settings of LPT1. Disable the device, and then view the icon that appears next to the device. Change the resource settings of a device from manual to automatic. Attempt to change the resources to different settings. Note what happens when you attempt to make this change. ■ Practice 3: Change Visual Settings in Windows Vista Download an image from the Inter- net, and set it as your desktop background using the Desktop Background item in the Personalization item in Control Panel. Do not right-click an image in Internet Explorer, and use the Set As Background option! Configure Windows Vista to use the Frost color and appearance. Configure Windows Vista to use the Classic Windows 2000 Theme. Configure and Troubleshoot Windows Aero ■ Practice 1: Perform a 3D Flip Perform a 3D flip to verify that Aero is functioning. ■ Practice 2: Aero and 16-bit Color After verifying that Aero is functioning, set the graph- ics adapter to use 16-bit rather than 32-bit color. Note the effect of this action on Aero. Take a Practice Test The practice tests on this book’s companion CD offer many options. For example, you can test yourself on just one exam objective, or you can test yourself on all the 70-620 certification exam content. You can set up the test so that it closely simulates the experience of taking a cer- tification exam, or you can set it up in study mode so that you can look at the correct answers and explanations after you answer each question. MORE INFO Practice tests For details about all the practice test options available, see the “How to Use the Practice Tests” sec- tion in this book’s Introduction. 149 Chapter 4 Configuring and Troubleshooting Internet Access When you install Windows Vista (as described in Chapter 1, “Installing Windows Vista Cli- ent”), the installation program asks you whether your computer is in a home, business, or public environment. If you choose a business or a public environment and setup detects an Active Directory directory service domain, your computer joins that domain and accesses the Internet through the business local area network (LAN). Exam Tip The 70-620 examination objectives do not specify Windows Vista as an Active Direc- tory client operating system. Examination 70-622 tests this configuration. In the home environment, or if your computer is part of a small business network that uses a workgroup rather than a domain, the computer is configured to access the Internet either through a direct connection to your Internetservice provider (ISP) or through another computer that provides Internet Connection Sharing (ICS). Your computer also might share its direct Inter- net connection with other clients in its workgroup. The Network And Sharing Center, accessible from Control Panel, together with software provided by your ISP, helps you configure Internet access. Internet Gateway Device Discovery And Control (IGDDC) is used when you enable ICS on your computer and turn on network sharing in the Network And Sharing Center. MORE INFO IGDDC For more information on IGDDC, search for “Using Internet Gateway Device Discovery and Control” in Windows Help and Support or access http://207.46.197.98/Windows/en-US/Help/670718ec-7d51- 49ed-87f1-b8a98ced11a41033.mspx. When access to the Internet is configured, your interface to the World Wide Web (WWW) is the Internet Explorer 7+ (IE7+) web browser. This chapter discusses how you configure IE7+ to provide access to appropriate web content by using Parental Controls and Content Advisor, how you subscribe to news feeds to obtain the latest information from websites that provide that service, and how you configure print and viewing controls. Exam objectives in this chapter: ■ Configure and troubleshoot parental controls. ■ Configure Windows Internet Explorer. 150 Chapter 4 Configuring and Troubleshooting Internet Access NOTE Internet Explorer 7+ This chapter discusses Internet Explorer 7+, as specified in the 70-620 examination objectives. If you want to download and use another browser, you are, of course, perfectly at liberty to do so.

You should also have a working connection to the Internet because this is required for Windows Vista installation. No additional configuration is required for this chapter. Real World Ian McLean I take the view that the Internet, and in particular the World Wide Web, is one of the best educational tools ever created. From the comfort and safety of their own homes and schools, children have access to more information than they could find in even the larg- est library—and kids who would never consider going into some dusty old library want to access the web. Of course the Internet is a dangerous place—just as the world is. Responsible parents and teachers ensure that the children in their charge do not access sites that contain content that they consider inappropriate, and carefully monitor the use of chat and bulletin board sites. Lesson 1: Configuring and Troubleshooting Parental Controls and Content Advisor 151 Lesson 1: Configuring and Troubleshooting Parental Controls and Content Advisor Parental Controls lets parents decide how their children use the computer. As an IT profes- sional you might be asked to advise parents on how to configure Parental Controls or to con- figure the facility for less computer-aware parents. You might need to answer more general questions related to Internet safety and safety strategies. This is one of the most significant areas of concern that purchasers of home computers have and they often need a lot of infor- mation and reassurance. You might also need to configure restrictions for your own children. MORE INFO Internet safety For more information on Internet safety, you should seriously consider purchasing the book “Look Both Ways: Help Protect Your Family on the Internet” by Linda Criddle and Nancy Muir (Microsoft Press, 2006) and reading it carefully. This inexpensive paperback gives you a lot of information that will help you in your chosen career. It might also help you protect your own children. Schools can also use Parental Controls to limit the web content, games, and programs that pupils can access on a per-child basis, although they are more likely to ask you to limit access to certain types of web content on a per-machine basis, in which case you would configure Content Advisor. You can configure Parental Controls to set limits on children’s access to the web, the hours that they can log on to the computer, and which games they can play and programs they can run. When Parental Controls blocks access to a webpage or game, the computer displays a notification. The child can click a link in the notification to request permission for access to that webpage or program. A responsible adult who has an account with administrator creden- tials can then allow access by entering a password. Thus a parent can control what his or her children can access. Content Advisor, a separate feature from Parental Controls in Windows Vista, works with web- sites that supply content ratings for potentially unacceptable content. When a user attempts to access such content or to access a site that has no ratings configured, IE7+ might block access depending on the Content Advisor settings. In this case a responsible person can allow access by supplying a supervisor password. You can also configure Content Advisor to permit access to sites that have no content ratings configured. Unlike Parental Controls, Content Advisor addresses only browsing the Internet and does not address broader parental concerns, such as time logged on, access to certain applications, and so on. It also works on a per-machine basis, not a per-user basis. [...]...
