5. Correct answer: B. During the logon phase programs are started and plug and play devices are detected.

A is not correct because kernel loading is the phase during which the Windows kernel is loaded into memory.

C is incorrect because initial startup is a very early phase during which the BIOS startup program attempts to find executable code from a boot device in order to begin starting the OS.

D is incorrect because POST, or power-on self-test, is a phase during which the CPU loads the BIOS program from ROMBIOS, and runs the POST tests on the system hardware.

E is incorrect because the boot loader phase is when the OS seems to really take control, switching the processor to protected mode, starting the file system, and discovering the location of the Windows OS files that need to be loaded into memory to start up Windows.

6. Correct answer: D. Any member of the local Users group may disconnect or reconnect an installed device. This is possible because this action does not remove the device driver for the device; it just makes the device unavailable.

E is incorrect because WINLOGON.EXE is the Windows logon service, which is started very late in the Windows startup process.

10. Correct answer: A. Startup and Recovery, a page in System Properties, is where you can modify the length of time the OS selection menu displays during Windows Startup.

B is incorrect because Device Manager, while a GUI tool, will not allow you to modify the length of time the OS selection menu displays during Windows startup.

C is incorrect because although BCDEDIT would allow you to modify the length of time the OS selection menu displays during Windows startup, it is a non-GUI tool and it is not available in Windows XP.

Answers to Essay Quiz

Answers will vary.

1. The actions that will create Windows registry changes are (only 5 are required by the question):

1) Windows starting up or shutting down

2) Running Windows Setup

3) Changing settings in a Control Panel applet

4) Installing a new device

5) Changing any Windows configuration settings

6) Changing user desktop preference

7) Installing or modifying an application

8) Making changes to user preferences in any application.

2. Start up Windows 7 using the Enable low-resolution video choice from the Advance Boot Options menu, which will use the installed video driver in a very basic video mode. Then, if this works, the new driver is not entirely bad, it just cannot handle the configuration and you should open Display Properties | Settings and reduce the screen resolution and/or color quality settings. If this option does not work, you should start Windows in Safe Mode, which does not use the installed video driver—it uses a very basic video driver. If Windows starts in Safe Mode, run Device Manager in Safe Mode, open the properties dialog box for the Display adapter, select the Driver tab and use the Rollback button to remove the updated driver you installed that caused the problem.

3. You access the Advanced Boot Options menu by pressing F8 during a startup. Once the menu appears, you have several startup options. These include Repair Your Computer(in Windows 7), three variations of Windows Safe Mode, several options for modifying a normal startup (enable boot Logging, enable low-resolution video (640x480), Last Known Good configuration, debugging mode, disable automatic driver signature enforcement (Windows Vista and Windows 7 only), start Windows normally (Windows Vista and Windows 7), and Reboot (Windows XP). In contrast, System Configuration (MSCONFIG) is a single utility that allows you to test many “what if” scenarios, by temporarily disabling programs or services to identify the source of a problem. Further, if you are not able to access the startup options menu with F8, but you are able to start Windows, use this utility to restart Windows in Safe Mode.

4. He can use Device Manager to view the status of devices, even though Windows XP will not allow him to actually make any changes unless he logs on as an administrator. If he starts Device Manager he will see a warning message that he does not have sufficient privileges to install or modify device drivers. However, if he clicks the OK button on this warning box, Device Manager will open, allowing a non-administrative user to look but not touch!

5. Boot logging occurs in all Safe Modes, but you can also select it from the Advanced Boot Options menu, which turns on boot logging, but starts the computer normally. In all cases, boot logging creates a log of the Windows startup in a file named NTBTLOG.TXT and saves it in the systemroot folder. This log file contains an entry for each component in the order in which it loaded into memory. It also lists drivers that were not loaded. You expect some drivers not to be loaded in Safe More, but when this occurs in a normal startup, it alerts an administrator to a possible source of a problem.

1. To isolate the problem to the network card, I would restart, press F8, and select Safe Mode from the Advanced Boot Options menu. Being able to start in Safe Mode does not isolate the problem to the network card, because that is one of several device drivers that aren’t loaded. It does indicate, that one of the components that was not started is possibly the cause of the problem. To isolate the problem to the network card, I would again restart, press F8 and select Safe Mode with Networking. This loads the networking components, including the network adapter driver. If it fails to start in this mode, the problem has been isolated to the network components. The most likely component is the network adapter. So, restart again, press F8 and select Safe Mode from the Advanced Options menu. Once in Safe Mode, run Device Manager, select the network adapter, and disable it. Restart once again, and allow it to start up normally. If the start up succeeds this time, the problem is isolated to the network adapter itself. Use Device Manager to perform whatever maintenance is appropriate. If the driver was recently updated, use Driver Rollback. If it needs an update use the Update option. If all else fails, uninstall the device driver and acquire a new driver or an entirely new adapter.

2. Demonstrate this by first restarting the computer in Safe Mode, describing the reason for doing so, and then restart in Safe Mode with Networking, explaining that if this failed, it would prove that the problem was with network components. Then, restart in Safe Mode, open Device Manager, and open the Properties of the network adapter and discuss the Driver Rollback and Update options.

Solution to Lab Project 7.2

Research will show that if, during bootup, Windows XP displays the error message NTLDR is missing, it indicates that the file NTLDR in the root of C: may be missing or corrupt. To solve this problem, the Windows XP computer must be able to boot from a floppy disk because you will need a Windows XP boot disk—a floppy configured to boot into Windows XP.

If there is another Windows XP computer with a floppy disk drive, format a floppy disk on that computer and then copy the NTLDR, , and BOOT.INI files to the floppy disk. Then, take the floppy disk back to the laptop and reboot the computer. If the BOOT.INI file is configured correctly you will be able to boot the computer, because NTLDR will load Windows from the location indicated in the BOOT.INI file.

Solution to Lab Project 7.3

1. You can back up the registry using System Restore, which will back up the entire system and settings, but the more targeted approach is to simply back up the key hierarchy that you are about to modify. The steps to do this are:

a. Open the Registry Editor and browse to the key in its location under the HKEY_LOCAL_MACHINE\SOFTWARE and right-click on it.

b. From the context menu select Export.

c. In the Export registry file dialog box, provide a name and location for the exported portion of the file and select Save.

2. Demonstrate the above steps.
