1. Verify the hardware connection

The error number 0xc00000e9 will appear on your PC’s screen if any of the devices connected to your Windows 11 machine are not properly connected.

It’s a good idea to go over the system for any damaged ports or equipment that isn’t firmly connected. You may proceed to the following step of disconnecting everything by starting with the mouse, keyboard, speakers, displays, printer, and other peripheral devices.

You may also try other RAM, graphics card, and other internal components on your motherboard combinations to see if they make a difference or if they are the root of the issue.

2. Run an SFC scan in a hurry.

  1. To enter the Search bar, press Windows + S, then type cmd, then right-click on the most relevant result to execute it as an administrator.1638518679_339_How-to-fix-Kernel-Security-Check-Failure-in-Windows-11
  2. Press Enter after typing or pasting the following command: sfc /scannow sfc /scannow sfc /s1638518680_954_How-to-fix-Kernel-Security-Check-Failure-in-Windows-11

When you’ve finished waiting for the procedure to finish, restart your computer (which could take some time).

3. Install the latest system drivers

  1. To launch the Settings app, press the Windows key + I, then choose Update & Security from the left panel, followed by Advanced settings on the right.1638518681_343_How-to-fix-Kernel-Security-Check-Failure-in-Windows-11
  2. Click on Optional updates after scrolling down to the Additional choices section.1638518682_508_How-to-fix-Kernel-Security-Check-Failure-in-Windows-11
  3. Select all of the driver updates that are provided to you, then click the Download & Install button.1638518683_875_How-to-fix-Kernel-Security-Check-Failure-in-Windows-11

Despite the fact that Windows is responsible for most driver updates, if you have a problem, you may manually search for updates. We highly recommend doing automated scans for out-of-date drivers with a professional application like DriverFix.

  1. To activate the search feature, press Windows key + S, enter cmd, then right-click on the most relevant result to execute it as administrator.1638518679_339_How-to-fix-Kernel-Security-Check-Failure-in-Windows-11

What can I do to maintain my hardware in good shape?

To begin, make a habit of cleaning and sanitizing your keyboard, laptop, and any other frequently used devices. 1640001693_629_How-to-fix-the-0xc00000e9-error-code-in-Windows-11

Cleaning your equipment with wipes is perfectly OK, but you should be careful about the wipes you use. Use electronic cleaning wipes that have been made specifically for this purpose to prevent inadvertently damaging your equipment.

Even the most careful among us will undoubtedly be confronted with a liquid spill at some time in their life. In this circumstance, quick action is critical: switch down your computer and unplug from the power supply as soon as the leak happens.

After that, start eliminating all of the excess liquid. It’s important to note that just because there’s no liquid visible on the top doesn’t imply it’s gone altogether.

Although we realize how tempting it is to work from the comfort of your own bed or sofa, we highly advise avoiding using your laptop on soft surfaces like mattresses, pillows, and other such objects.

Working on hard, well-ventilated surfaces is preferred than working on soft ones. If you place your smartphone on a soft surface, it may overheat, which is particularly harmful during video calls.

Restarting your computer on a regular basis is also a good idea. To keep your computer working properly, we suggest restarting it at least once a week. This assists in the deletion of stored data and the memory reset of your machine.

While we’re on the topic of memory management, ensure sure your laptop’s burden is manageable. To avoid harm, make sure your PC has a hardware diagnostic tool installed.
