If your Windows computer is not booting up and displays Secure Boot Violation – The system found unauthorized changes on the firmware, operating system, or UEFI drivers error message on the screen, then you can follow this tutorial to troubleshoot the problem.
When you encounter this kind of problem on your computer, you will get the following error message on your screen:
“Secure Boot Violation
The system found unauthorized changes on the firmware, operating system, or UEFI drivers.
Press [OK] to run the next boot device or enter directly to BIOS Setup if there are no other boot devices installed.
Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.”
This kind of error message pops up due to the Secure Boot that protects your computer from running any non-OEM signed boot software during startup. In other words, the Secure Boot firmware is the one that scans for non-signed boot software each time your computer boots up and if it detects anything strange, it will block the boot and will display the error message. To fix this error, there are two things you can try. You can try to disable the Secure Boot or try using a System Restore Point. For more detailed instructions, refer to each one of the options provided below.
Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:
Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.
To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.
Error CausesThe CompareExchange128 error normally occurs due to two possible reasons:
One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.
NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.
Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b
This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:
If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:
If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.
If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.
“Windows could not search for updates, Code 0x800F0922 Windows Update encountered an unknown error” Or: “Windows failed to install the update with error 0x800F0922”This issue might be caused by two possible reasons such as:
Error CausesError code 80070103 affects Windows users who attempt to access the latest updates for hardware drivers using Windows Update. Windows 10 users who are affected by this error code will be unable to complete the upgrade process. This error code usually occurs due to the Windows Update attempts to download an incompatible version of a driver or a driver that is already downloaded on one’s device.
Error CausesThe cause of error code 80070103 in Windows 10 is usually easy to determine. This is due to the fact that the error code only affects users who attempt to access updates related to hardware drivers. In such cases, the error code will only occur if the Windows Update website or tool on your machine attempts to install a driver that is already present on one’s machine or the version of the driver is unsuitable for one’s machine due to lower compatibility.
Manual repair methods are very effective in helping Windows users fix problems related to error code 80070103 as well as other errors. These repair methods can usually be implemented by users with very limited technical skills. In some cases, however, you may need to contact a Windows repair technician, i.e. if you have problems following the manual repair method instructions provided or if the repair methods prove unsuccessful.
In the case of error code 80070103, the problem can be rectified by either hiding the update or reinstalling the hardware driver. Windows users can hide an update on the Windows Update website or via Windows Update within their machine’s Settings. However, users will need to contact their device manufacturer to reinstall hardware drivers in most instances. See below for further details regarding these manual repair methods.
In the case where you are informed via an error message box that a driver, for instance, your graphics driver, is incompatible you may need to consider hiding the update to prevent error code 80070103 from reoccurring on your machine.
The incompatible issues will come about when the Windows Update website attempts to download a driver that is already on the device or one with a lower compatibility. When you hide the update, it is in essence, preventing Windows Update from offering this driver in the future. To complete this manual repair method, follow the steps below:
You may also complete this process by opening Windows Update within your computer’s settings, then selecting the Optional update or available link. Once you’ve done this, you may then select the updates you would like to install and hide the update that has resulted in the occurrence of error code 80070103.
In the case where you need to install a hardware driver, you will need to contact the manufacturer of your device. Once you’ve contacted the manufacturer or visit the manufacturer’s official website, you can then install the latest device drivers manually. Read the instructions for the installation of the latest drivers carefully. This will ensure you avoid any problems and improve your chances of successfully fixing error code 80070103.
After you’ve contacted your device manufacturer and completed the process of reinstalling the hardware driver, check Windows Update to see whether or not error code 80070103 has been rectified. If the problem was related to your hardware driver and you successfully reinstalled the driver, the error code will not reoccur when you attempt to download the latest updates for your hardware drivers.
However, you may need to take another approach if this manual repair method fails to fix error code 80070103. For instance, consider getting help from a Windows repair technician who is equipped with the skills and expertise necessary to offer a detailed inspection of your machine. Though the error code is related to one’s drivers, the fact that a Windows error code occurred may mean that your system needs a thorough evaluation as other issues may be present.
