Module Review and Takeaways
Question: After installing a new video driver, your user’s computer becomes unstable and will not start
correctly. What would you try first to resolve this problem?
Answer: There are various options you can use to resolve the problem. You should try the easiest
approach first. If you can still see the desktop, you should attempt a driver rollback first. If the desktop is not visible, you can restart the computer in low-resolution video and then use driver rollback. You also can start the computer in safe mode and then use System Restore.
Question: The boot environment of a user’s computer is corrupted, and you suspect a virus. Before you
can run virus removal tools, you must repair the boot configuration. What command-line tool or tools could you use?
Answer: You can repair the boot configuration by using the bootrec.exe command with the fixmbr and fixboot switches.
Question: You add a new hard disk to the computer, which changes the computer’s partition numbering.
To enable the computer to start, you need to change the BCD. What tool can you use to change the BCD?
Answer: You can use BCDEdit /enum to view the entries in the store. Then, you can use BCDEdit to edit
the store to reflect the changes in the computer configuration.
Question: A user has reported a problem to the help desk. The user is experiencing problems with
starting a computer after a new device driver was added. You decide to start the computer by using a minimal boot, but you want to configure that from the Windows operating system before restarting. What tool could you use?
Answer: You can use the System Configuration (MSConfig.exe) tool to configure advanced startup
options, including various minimal startup environments.
Question: A system service is causing startup problems, and your help-desk user has started the
problematic computer in Windows RE. What command-line tool can you use to modify service startup type?
Answer: You can use Sc.exe to view and configure system services within Windows RE. You also can
modify service startup type by using this command.
Question: The help desk recently installed a new device driver on a computer. A stop code is generated
and a blue screen is shown during computer startup. What recovery mechanism would you try first?
Answer: You could try starting the computer in safe mode and use a driver rollback if the computer is
able to start from the hard drive. Alternatively, you can use Windows 8.1 media and Windows RE to apply a system restore point. You also could use Refresh your PC as one of the last recovery steps.
