Question: How Do I Start Windows Using Last Known Good Configuration?

Starting Windows using Last Known Good Configuration (LKGC) is very often the best first step when troubleshooting a Windows startup problem.

As the name implies, starting Windows using Last Known Good Configuration starts Windows using the registry and driver configuration that worked the last time Windows was started and shut down properly.

Since drivers and registry issues are common reasons why Windows won't start, Last Known Good Configuration can be a very valuable tool in troubleshooting Windows startup issues.

Answer: You can start Windows using Last Known Good Configuration from the Advanced Boot Options menu.

Starting Windows using Last Known Good Configuration is pretty simple but the exact method differs a little depending on which Windows operating system you're using:

Last Known Good Configuration is not available in Windows 8.

In most cases, if your Windows startup problem is not solved by starting with Last Known Good Configuration, the next step would be to attempt a System Restore. However, if you came here from a specific troubleshooting guide, your best bet is to follow whatever troubleshooting step is listed next.

Important: The changes made when starting Windows using Last Known Good Configuration can not be undone. Don't let this deter you from trying Last Known Good Configuration - a working Windows with the previous session's driver and registry data is much better than Windows that you can't access at all.
