How to Fix Kernel Auto Boost Invalid Lock Release Error

If your Windows computer suddenly shows a blue screen (BSOD) with the error message “Kernel Auto Boost Invalid Lock Release” you are not alone. Many users come across this unclear error while watching videos or playing games, often without knowing why their computer crashed suddenly.

In simple terms, this error happens when a system “lock” — which allows a thread to access a resource — is released improperly. This means a thread tries to release a lock that it never actually acquired in the first place.

In this guide, we will walk you through what the Kernel Auto Boost Invalid Lock Release error means, and how you can fix it safely — even if you don’t have a technical background.

What is Kernel Auto Boost Invalid Lock Release?

Kernel Auto boost Invalid Lock Release is a Blue Screen of Death (BSOD) error with the technical code 0x00000162.This error happens when a thread releases a lock that was being tracked by AutoBoost, but that thread did not actually have control of the lock in the first place.

To understand it more easily, imagine a situation where only one person is allowed to hold the key to a meeting room while they are inside. If someone else tries to return the key without being the one who had it, it causes confusion. Similarly, in Windows, this error occurs when the system encounters an unexpected release of a memory lock, leading to a crash.

Boot into Safe Mode (If Your PC Keeps Showing the BSOD)

If your computer keeps restarting with the Driver Overran Stack Buffer error each time you turn it on, you might not be able to apply fixes through the normal Windows. In such a situation, you should boot your PC into Safe Mode, which starts Windows with just the necessary drivers and services.

Steps to enter Safe Mode in Windows 11/10:

Turn on your PC and force it to shut down as soon as the Windows logo appears. Repeat this process three times.
Windows will open the Automatic Repair screen.
Select Advanced options > Troubleshoot > Advanced options > Startup Settings > Restart.
After your PC restarts, press the number 4 or the F4 key to start in Safe Mode, or press 5 or F5 to start in Safe Mode with Networking.
After you are in Safe Mode, follow the troubleshooting steps listed below.

Why this works: Safe Mode starts Windows with only the necessary drivers and services, which makes it easier to remove problematic drivers, install updates, or repair system files without experiencing repeated Blue Screen of Death (BSOD) errors.

Note: If your PC starts normally and only displays the BSOD occasionally, you can skip this section and proceed with the fixes below.

How to Fix Kernel Auto Boost Invalid Lock Release

Follow the steps outlined below in order.Each method is considered safe, but warnings are given prior to any steps that may involve risk.

1. Restart Your PC and disconnect non-essential hardware

Turn off your computer and unplug all unnecessary external devices, such as USB drives, additional monitors, and Bluetooth adapters.
Turn the computer back on and use it as usual.
If the issue does not happen again, it was likely caused by one of the connected devices.

This method works because sometimes the drivers for external devices can interfere with the system’s operations. By temporarily disconnecting these devices, you can check if the problem is related to the hardware.

2. Uninstall and Reinstall Network Adapter Drivers

Press Win + X keys on your keyboard and choose Device Manager.
Expand the Network adapters section and find your Wi-Fi or Bluetooth adapter.
Right-click on the adapter and click Uninstall device, then restart your computer—Windows will automatically reinstall the adapter.

This works because outdated or faulty drivers can cause this error, as they may not properly release their locks. Uninstalling the adapter and letting Windows reinstall the driver fixes this issue.

3. Disable Overclocking

Enter the BIOS/UEFI by pressing the manufacturer-specific key (such as Del, F2, or F10) while restarting your PC.
Find the overclocking settings for the CPU, GPU, or RAM and change them back to “Default” or “Optimized Defaults.”
Choose the “Save and Exit” option, then restart your computer normally. After the restart, check if the error still happens.

This method works because overclocking makes system components run faster than they are designed to, which can cause system crashes. Returning to default settings helps restore normal and stable system performance.

Warning: When adjusting BIOS settings, only modify the overclocking-related options. If you are not sure about the settings, use the “Load Optimized Defaults” option and avoid making any other changes manually.

4. Troubleshoot in a clean boot state

Press Win + R at the same time, type msconfig into the box, and press Enter.
Navigate to the Services tab, check the “Hide all Microsoft services” box, and then click “Disable all.”
Next, open Task Manager by pressing Ctrl + Shift + Esc, go to the Startup tab, disable all startup programs that are not from Microsoft, and then restart your computer.

This method works because a Clean Boot starts the system with only the essential Microsoft services running. This helps identify if a third-party application or background service is causing the error.

5. Perform a Power Cycle (Hardware Reset)

Turn off the computer entirely and remove the power cable from the back.If it is a laptop, also take out the battery if you can.
Unplug all other connected devices, leaving only the keyboard, mouse, and monitor attached.
Hold down the power button for about 15 to 20 seconds to remove any leftover electricity from the system. After that, plug everything back in and turn the computer on as usual.

This process helps by clearing any remaining electrical charge in the system, which can sometimes lead to small hardware issues. It is a safe and harmless way to reset the hardware.

6. Replace the faulty hardware component

If none of the steps mentioned earlier solve the problem, try removing the RAM modules one at a time (if multiple sticks are installed) to identify any faulty ones.
Press the Win + R keys together, type mdsched.exe, and run the Windows Memory Diagnostic tool to check the RAM for issues.
If a specific component, such as the RAM, GPU, or storage drive, is found to be defective, it should be replaced.

This method works because the error may be caused by faulty hardware, especially the RAM. By identifying and replacing the faulty part, the underlying problem is resolved permanently.

Warning: Replacing hardware should be considered only after all software solutions have been tried. If you are not experienced with hardware handling, it is advisable to get help from a qualified technician.

Conclusion

There is no need to get worried when you see the Kernel Auto Boost Invalid Lock Release error. In most situations, this issue can be fixed by updating your drivers, resetting your overclocking settings, or performing a Clean Boot. Follow the steps provided in the order given, and if one method does not resolve the problem, try the next one.

To help prevent this issue in the future, make sure to keep your drivers up to date, overclock your computer only within safe limits, and keep an eye on your system after connecting any new external devices. These steps can help maintain your computer’s stability and lower the chances of experiencing such BSOD errors.
