You are working as a Technician at Certkiller .com. You have just finished installing a new device
driver on you boss’s workstation, but the Windows XP operating system became unstable. The
system is still unstable after a second reboot and choosing Last Known Good Configuration. This
occurs because:
A.
the Last Known Good Configuration only works for hardware devices and any software changes
are not applicable.
B.
the system’s registry should have been saved prior to the installation of a device driver by using
the System Restore application.
C.
the Last Known Good Configuration could not find a valid Restore Point since the System
Restore was not run prior to the installation of the Device Driver.
D.
the system’s registry is overwritten after every login and the settings on the initial install were
overwritten after the first reboot and login.
Explanation:
After a user has successfully logged in to the machine, Winlogon does the following:
* Updates the Control Sets ; the LastKnownGood control set is updated to reflect the current
control set.
* User and Computer Group Policy settings are applied. * Startup programs are run from the
following locations:
1.HKLM \SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
2.HKLM \SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run
3.HKLM \SOFTWARE\Microsoft\Windows\CurrentVersion\Run
4.HKCU \Software\Microsoft\Windows NT\CurrentVersion\Windows\Run
5.HKCU \Software\Microsoft\Windows\CurrentVersion\Run
