5. Update Drivers

As we mentioned before, incompatible drivers may also cause “Kernel Security Check Failure”. While Windows generally handles driver updates, it is possible to manually look for updates if you experience an error. There are three methods you can update your drivers on your computer and we’ve included the three methods below.

NOTE: We have taken the example that the driver displays to aid you in understanding the idea. Once you’ve mastered the concept then you can upgrade all other drivers too.

Update Drivers with Device Manager

Then, press Windows + S to open the menu ‘Search’, enter ‘Device Manager” in the text box at the top, then click on the appropriate search result to open it.

Within the Device Manager Find the option ‘Display adapter Double-click it to expand it and show the devices that are under it.

In the Update Drivers window that pops up you’ll have two choices: or allow Windows look for the most suitable available driver on your system and install it , or find and install it manually. It is recommended to select the first option, and let Windows handle updating the drivers.

If you have installed an update and you are able to verify that the ‘Kernel Security check Failure’ error has been resolved. If Device Manager is unable to locate a new driver, we should move to the next step to update the driver.

Install Driver Updates using the Windows Update Menu

Although Device Manager only looks for driver updates for your system Windows Update looks for driver updates that are available through Microsoft. These are updates that have been submitted by the device manufacturers to Microsoft by the manufacturers of devices and made available to users via Windows Update.

To update your drivers using Windows Update, launch the “Settings” app as described earlier, and then select ‘Windows Update from the tabs to the right.

Then, select “Advanced Options” to the left.

Then, find the option ‘Optional updates’ and click under the “Additional options”.

NOTE: Next to ‘Optional updates’, you’ll see the number of updates that are available in the case of 1 in the example below. If there are no updates available, simply skip the next steps and move to the next step.

It is recommended to take the time to download these patches and then install them. To do this, mark the checkboxes that apply to each update and then click ‘Download and install’ beneath the respective updates.

Once the updates have been installed and the computer is restarted, you will be you are prompted. After the computer has restarted then check to see if the issue is resolved.

If you didn’t see any updates on Windows Update, it doesn’t necessarily mean that the update is not available. Therefore, it’s time you go to the last method to update your driver.

Download the latest drivers from the Manufacturer’s Website

The final place to look for the driver update is on the manufacturer’s site. A lot of manufacturers do not submit drivers updates directly to Microsoft instead, they upload them to their official site for download by users so you won’t see the updates on Windows Update.

Before downloading a driver upgrade on the manufacturer’s site You must determine the current version of the driver to determine whether the version you have downloaded is an update version. To determine the current driver version, click on your device’s name in Device Manager, and select Properties in the contextual menu.

In the device’s properties, click on the tab ‘Driver’ and note the driver’s version.

Go to Google or another search engine and look to update the driver by using the words ‘Device Manucaturer” and “OS” as keywords to search for, then ‘Driver Update’.

Find the official site of the manufacturer by searching the result. verify if an update is available. If there is one you can download it. Once you’ve downloaded the update driver, click on the downloaded file to launch the installer. Follow the instructions on screen to finish the installation process.

Once the installation has been completed and the computer is restarted, you will be you are prompted to allow the modifications to take effect. Check if the ‘Kernel Security Check Failure issue is resolved.

6. Roll Back Driver Update

Sometimes an update to a driver can cause errors on Windows. If you’ve noticed the ‘Kernel Security Test Failure error following the update of the driver in question, then it’s about time to roll back to the prior version. Windows provide a quick way to go back to the prior driver version. Here’s how to do it.

To reverse an update to a driver, right-click on the device where the driver was recently updated and choose ‘Properties’ in the contextual menu.

In the device’s properties go to the Driver tab at the top, and then click “Roll back Driver’.

NOTE: If you find the “Roll Back Driver option grayed out, it’s because the driver wasn’t last updated or Windows did not store the files from the previous version. In this scenario, you’ll need to download the previous version on the manufacturer’s site in the manner we discussed earlier.

Then, choose a reason to roll forward the update, and select “Yes” at the bottom of the page to continue.

The update will be reversed and the old version will be installed. Verify if this resolves the ‘Kernel Security Test Failure’ error.

7. Check your computer for viruses
