How to Fix Windows Update Error 0x800B010A
We will try to fix it by troubleshooting different Windows update aspects and if that fails, we will manually install the update or perform an in-place upgrade.
1. Check for Windows Updates Again
You will see the Windows update error 0x800B010A notification if an ongoing update locked a system resource or a prerequisite update was not installed on the system. Here, checking for Windows updates again will solve the problem.
2. Perform a Clean Boot of the System
You will fail to update your system with the 0x800B010A error if another process or service on your system is locking the access of OS components to essential resources. To check this, perform a clean boot of your system.
3. Hide the Problematic Update
If the problematic update is for another manufacturer but you have a system from another manufacturer (e.g., a Dell PC is offered an HP keyboard driver update), then that update does not apply to your system and you should hide it. Remember only hide the update if it does not apply to your system.
4. Reset Windows Update Components
Windows Update components are responsible for completing Windows updates on your system. If any of these components is malfunctioning or gets damaged, the update process will fail with the error at hand. To solve this, reset Windows Update components.
5. Disable or Uninstall the Antivirus
You will fail to complete Windows Update with error 0x800B010A if your system’s antivirus is hindering the operation of updates. To fix this, disable or uninstall the system’s antivirus. Warning: Advance with extreme caution and at your own risk as disabling or uninstalling the system’s antivirus may expose the system and data to threats.
Disable the Antivirus
6. Uninstall the Antivirus
7. Manually Install the Problematic Update or Perform a Repair Install of Windows
As the Windows Update is failing to install the problematic one, manually installing the same will do the trick. If this fails, then performing a repair install of the PC’s Windows will get the job done.
8. Export and Import Certificates
If a required certificate is not valid or gets damaged, the update process will fail to authenticate it and as a result, will stop Windows update installation, thus causing the error 0x800B010A. In this scenario, exporting the certificates from a trusted system and importing them into the problematic system will clear the error.
9. Restore Your System or Reinstall Windows
Windows update will fail with error 0x800B010A if a recent change to the system has made the system incompatible with the update. To fix this, restore the system to an earlier date (if a backup is available). If this does not work, perform a clean installation of Windows on your system. If the issue persists after the clean installation, contact Microsoft Support.
