Start out the lecture with Windows Explorer open and be prepared to locate the registry files as you discuss them. Then, a Try This activity involves running Registry Editor in order to view the registry structure. he objective of this section is to give the students an understanding of the function of the registry, its pieces and parts, and the location of registry hive files. e don’t encourage them to actually modify the registry, but to understand that many things they do day-to-day modify the registry. Step-by-Step 7.01 guides them through using System Restore to create a restore point, an indirect way to back up the entire registry and more. This section concludes with a brief description of how to backup just a portion of the registry using Registry Editor.
Open REGEDIT during this part of the lecture, and instruct the students to follow the instructions in the Try This on page 245 to open this program and view the registry structure. Then demonstrate the hierarchical structure of the registry and point out the key points. This section has several key terms. Be sure to use the text and the REGEDIT program to differentiate among these registry components.
Step-by-Step 7.01 guides the students through using System Restore to create a restore point, an indirect way to back up the entire registry and more.
Explain that at every startup the Windows OS is &quot;rebuilt&quot; from the ground up through six phases. Then continue with the description of these phases. Also, point out that Beginning with Windows Vista, the Windows files involved in the Windows startup changed, and that the text describes the differences.
Point out that the Windows Vista/Windows 7 BOOTMGR and WINLOAD.EXE files together replace the functions of the old NTLDR file. These newer versions of Windows do not need NTLDR, BOOT.INI, and NTDETECT.COM, but BOOT.INI and NTDETECT.COM will be present on a computer that multi-boots between an old OS and Windows Vista or newer.
Emphasize that much happens during the logon phase in addition to logon
This example is not in the book.
Step-by-Step 7.02 Modifying System Startup for Windows 7. Point out that, as with previous versions of Windows, you can modify some startup settings through the GUI, which this exercise demonstrates. Beginning in Step 4, they will also run BCDEDIT to see the contents of BCD, including the change made through Startup and Recovery.
Allow the students the few minutes required to complete the Try This on page 257. If this is not possible, demonstrate it for them.
Windows 7 new Device Stage features provides a “home page” for each device in Devices and Printers.
Step-by-Step 7.03 Getting to Know Device Manager. This exercise has you first create a desktop shortcut to Device Manager. Those using Windows 7 can add an extra step between Steps 2 and 3 and pin Device Manager to the taskbar by simply dragging the new shortcut there. Then delete the desktop shortcut. If you are “lucky,” Device Manager will create a teaching moment by revealing a problem with a device. Be prepared for such a moment by testing this exercise on the lab computers before class and determining a course of action so that you can demonstrate how to solve any discovered problem. Try to hold off on solving the problem until you move into the Troubleshooting section.
The System Recovery Options screen (accessed from Repair Your Computer) is shown in Figure 6-11 on Page 203 in Chapter 6.
Safe Mode (plain): If Windows will not start normally, but starts up in Safe Mode, see note below under Safe Mode with Networking to determine if the problem is related to a network component (usually the network adapter card). Then use Device Manager (in Safe Mode) to try to determine the problem. Safe Mode with Networking: If Windows will not start normally, but starts up in Safe Mode, then restart and select Safe Mode with Networking. If it will not start in Safe Mode with Networking after previously starting in Safe Mode, the problem is related to a network component (usually the network adapter). If the problem appears immediately after installing a new adapter driver, uninstall it and find a new driver. If it appears after an upgrade of the driver, open Device Manager in Safe Mode and roll back the driver. Safe Mode with Command Prompt: If Windows will not start normally, and will not start at all in Safe Mode, then restart and select Safe Mode with Command Prompt.
Step-by-Step 7.04 Using Windows in Safe Mode: This exercise gives the students experience restarting Windows in Safe Mode, and has them browse through Windows Help and Support, which displays by default in Safe Mode in Windows 7. This shows them the recovery tools they can easily access while in Safe Mode.
Open MSCONFIG, following the Try This on page 270, and give the students a tour of the myriad settings they can modify. This is a great “what-if” tool for testing various scenarios when troubleshooting. Show them how you can also use this tool to select Safe Mode (by another name). If time permits, demonstrate using this to modify startup and restart your system. Then, again time-permitting, have the students do this on their own, as described in the Project at the end of this Chapter’s Instructor Manual.

The registry is a database of all configuration settings in Windows. Avoid directly editing the registry, because you can cause severe damage. The Control Panel applets provide a safe way to edit the registry.
Windows creates the registry during setup and modifies it any time a setup or installation program runs after that, and during startup and shutdown. Windows also modifies it anytime it installs a device driver and whenever it configures any application, Windows component, or device.
If necessary, modify system startup using the Startup and recovery page in System Properties. You can also modify the BOOT.INI (Windows XP) and BCD (Windows Vista/ Windows 7) files directly to modify startup, but only very advanced techs should do this.
A device driver is program code, created by the device manufacturer, that allows an OS to control a physical device. Look for device drivers on the disk or CD that comes with a device or at the Web site of the manufacturer.
When an administrator installs or connects a plug-and-play device to a Windows computer, the computer will automatically detect the device, and install and configure the driver with little or no interaction from the user, except to provide the device driver disk if requested.
Windows offers a variety of startup options, and some are well suited for troubleshooting. These include the Advanced Boot Options menu and the System Configuration utility. Both allow you to select from several options for restarting Windows.
Device Manager is the primary tool for troubleshooting device problems. A yellow exclamation mark on a device in Device manager indicates a problem. Open the properties dialog box to see an explanation.
