If you’re asking yourself how to boot Windows 10 into the “Last Known Good Configuration” mode, the short answer is that you’re out of luck. Microsoft has removed this specific boot option, however, many other options are still available through Advanced Recovery options.

Our article will describe what the “Last Known Good Configuration” boot option is and how you can boot your computer using it in Windows 7.

We’ve also included some useful tips or Windows 10 users on using Safe Mode, a great alternative to the “Last Known Good Configuration” recovery option.

What is the Last Known Good Configuration and what can you fix with it?

Even though Windows 7 is an extremely popular and acknowledged operating system, it has its issues. Sometimes after a failed update, a misconfigured system setting, or a faulty driver installation, you can essentially lose access to your computer.

This is also true if your device was infected by malware. Let it be a simple virus, spyware, or ransomware, your computer can get locked away from you easily.

Recovery options allow you to get back into your system even if the normal way doesn’t seem to be working. One of these recovery options is the “Last Known Good Configuration,” which is used to load the last version of Windows 10 that successfully booted up. You can use it to fix the following issues:

  • Failed installations of drivers. When you fail to install a driver correctly, your computer may go into a BSoD (Blue Screen of Death) state on startup. This is going to entirely lock you out of your computer without proper troubleshooting.
  • Faulty Windows updates. If your computer was unable to fully or correctly apply a Windows 10 update, you may become locked out of it.
  • Malware infection. One of the most dangerous types of malware is one that locks you out of your device. If your computer is infected, you can use recovery options to remove the malware.
  • Hardware or software conflicts. Recently installed applications and hardware components may conflict with already existing ones. If this is the case, you can fix the issue by booting in the “Last Known Good Configuration.”
