What should you do if Windows 2000 will no longer boot after registry changes?

• A. Reinstall the operating system
• B. Reboot using F8 and select "Last Known Good Configuration"
• C. Use the recovery console to restore the registry
• D. Perform a system restore from a backup

Answer: (B)

The choice to reboot using F8 and select "Last Known Good Configuration" is valuable because it provides a straightforward way to revert the system to a previous state where it was functioning correctly. When changes are made to the Windows registry, it can sometimes lead to issues that prevent the operating system from booting properly. The "Last Known Good Configuration" option uses a backup of the system registry and device driver settings from the last time the operating system started successfully. By selecting this option, you are effectively telling Windows to load these previously successful settings, which can often resolve issues caused by recent changes to the registry. This approach is less invasive than reinstalling the operating system, as it avoids potential data loss and the need to reinstall applications. While using the recovery console to restore the registry and performing a system restore from a backup are also viable options, they may require more technical know-how and preparation, such as having access to installation media or a backup system in place. Therefore, opting for the "Last Known Good Configuration" makes it a convenient first step in troubleshooting boot issues caused by registry modifications.
