How to fix KB5012170 fails to install on Windows?

Issue: Hello. For the past two weeks, I have been trying to install KB5012170 on Windows 11, but to no avail. Every time I try it, the update fails with an error 0x800f0922. Any tips that could help me with this? Thanks.

Solved Answer

Windows was upgraded to service with the release of the Windows 10 version back in 2015, which meant that Microsoft was bound to deliver regular updates at a certain pace. To be more precise, users could expect new features, security vulnerability patches, improvements to the existing aspects, and bug fixes regularly.

Microsoft releases updates on the second Tuesday of every month, which is broadly known as Patch Tuesday[1] by many. On August 9, 2022, the KB5012170 update was released and was meant to fix many well-known issues, such as security vulnerability that the attackers could exploit when the UEFI-based system was loaded via the Secure Boot option.

The update was released for various Windows operating versions, including Windows 11, 10, and 8. Unfortunately, regardless of the versions of the OS users were employing, some people suffered from the KB5012170 installation errors, which prevented them from patching their system with a rather important security patch. People reported receiving a 0x800f0922 error code, although this may vary.

How to fix KB5012170 fails to install on Windows?

Several reasons may cause the issue to arise; for example, if you have Secure Boot enabled, you will like to fail to install the update because the bootloader is missing security patches. In this case, installing the latest UEFI/BIOS update would fix the issue.

If you are experiencing KB5012170 installation failures with other error codes or no code at all, other solutions provided by us could help. Before proceeding, we recommend scanning the system with a powerful FortectMac Washing Machine X9 repair tool, capable of finding damaged system components and repairing them automatically, ultimately resolving BSODs, DLL errors, and similar common issues.

Tip 1. Update BIOS

If you are facing the 0x800f0922 error whenever you try to update your device, the issue lies within the outdated UEFI/BIOS[2] version.

  • Type in System Information in Windows search and hit Enter
  • Note down info next to BIOS Version/Date and BaseBoard Product
  • Open your web browser and visit the official site of your motherboard manufacturer
  • Head to the Downloads section
  • Download the appropriate version of BIOS for your motherboard and launch the installer
  • Reboot your system once complete.

Update BIOS

Some device manufacturers (especially laptops) provide utility tools that could have the BIOS update section included, so check if such software exists for your computer.

Tip 2. Disable third-party security software

To repair damaged system, you have to purchase the licensed version of Fortect Mac Washing Machine X9.

While it is not easy to determine what is causing Windows update installation errors, there are certain aspects that could be applied to most cases. This is why we recommend disabling a third-party security tool if such is running on your device. Once such an app is installed, it changes certain aspects of the OS on the kernel[3] level, which changes how Windows responds to certain behaviors, and software/update installations are one of those.

You can either disable the real-time protection feature on your anti-malware or temporarily uninstall the app. Both methods work, and it is a matter of your preference. Once done, you should initiate the download and installation process of the KB5012170 update and see if it resolves the problem.

Tip 3. Check for system file corruption

Update errors can frequently occur due to system files that got corrupted. You can remediate this issue by running commands via elevated Command Prompt as follows:

  • Type cmd in Windows search
  • Right-click on Command Prompt and pick Run as administrator
  • When User Account Control shows up, click Yes
  • Use the following command lines, pressing Enter after each:
    sfc /scannow
    DISM /Online /Cleanup-Image /CheckHealth
    DISM /Online /Cleanup-Image /ScanHealth
    DISM /Online /Cleanup-Image /RestoreHealth
  • Restart your computer.

Run SFC and DISM

Tip 4. Run Windows Update Troubleshooter

  • In Windows search, type in troubleshoot and press Enter (you can also go to Start > Settings > System > Troubleshoot)
  • Pick Other trouble-shooters (in Windows 10, pick Additional troubleshooters)
  • Scroll down to locate the Windows Update option and click Run
  • Wait till the scan is finished, apply the changes, and try running the update process once again.

Run Troubleshooter

Tip 5. Install manually

You can attempt to install the update manually.

  • Go to Microsoft Update Catalog
