It is possible to troubleshoot your computer when something goes wrong. If certain settings or drivers cause problems, you can always boot into the “Last Known Good Configuration” (LKGC) on Windows 10. This feature will help you restore your computer to a functioning state and get rid of any system errors. 

In this article, we will discuss what the Last Known Good Configuration is and how to use it in Windows 10. 

What is the Last Known Good Configuration?

First things first, what exactly is this ‘Last Known Good Configuration’? When your PC boots correctly, it saves the current system settings as the ‘Last Known Good Configuration’. This is a snapshot of your system when everything was running smoothly. Think of it as a digital superhero, ready to rescue your system from the clutches of malfunctioning updates or drivers.

The Shift from Windows 7 to Windows 10

Do you recall the fond memories of Windows 7? Booting into the Last Known Good Configuration was as simple as hitting F8 during startup. But, Windows 10 doesn’t make it that easy. It’s like upgrading from a bicycle to a sports car – sure, it’s faster and sleeker, but it’s also a bit more complex. However, don’t be disheartened by this! With some assistance, we’ll swiftly get you back on course.

Preparing to Boot into the Last Known Good Configuration

Let’s buckle up and get ready for our journey into the past. Before we begin, it’s important to understand that Windows 10 doesn’t have a built-in option for the Last Known Good Configuration. But don’t panic! It has something even better: ‘Advanced Startup Options’. This is like your personal toolbox, filled with a variety of tools to solve different problems.

Accessing Advanced Startup Options

You can access Advanced Startup Options in two ways: from the Settings menu or by using a Windows 10 installation disc or USB drive. 

From the Settings Menu:

  1. Click on the Windows icon and select ‘Settings’.
  1. Choose ‘Update & Security’
  1. then ‘Recovery’.
  1. Under ‘Advanced startup’, click ‘Restart now’.
  1. After your PC restarts, select ‘Troubleshoot’ > ‘Advanced options’.

Using a Windows 10 Installation Disc or USB Drive:

  1. Insert the disc or USB drive and restart your PC.
  2. Press any key to boot from the disc or drive.
  3. Select your language preferences, then click ‘Next’.
  4. Click ‘Repair your computer’, then select ‘Troubleshoot’ > ‘Advanced options’.

Booting into the Last Known Good Configuration

Now that we’ve reached our toolbox, it’s time to pick the right tool. In this case, we’re looking for ‘System Restore’. This is the magic stick that will transport us back to the last known good configuration.

  1. In the ‘Advanced options’ menu, select ‘System Restore’.
  2. Choose your username and enter your password.
  3. Follow the prompts to choose a restore point (the last known good configuration).
  4. Confirm your choice and let Windows do its magic!

Keep in mind that System Restore won’t impact your personal files, but it will eliminate apps, drivers, and updates installed subsequent to the creation of the restore point. It’s a small price to pay for a functioning system, don’t you think?


Experiencing problems with your Windows 10 system can feel like being stuck in quicksand. But now you know that there’s a lifeline you can throw yourself: booting into the Last Known Good Configuration. It may not be as straightforward as hitting F8, but with the Advanced Startup Options, you’ve got a whole toolbox at your disposal.
