4] Disable/Uninstall 3rd party security software
Firewall and antivirus programs are important for system safety, but they can sometimes interfere with Windows and cause this error to appear.
Third-party AV suites are all known to cause this particular issue. In this case, to fix this issue, you’ll have to remove all third-party antivirus programs from your PC using the dedicated removal tool to remove all files associated with your antivirus program. The reason is, it’s much more efficient and invasive to use the custom uninstall tools for the AV program from the manufacturer, if available, whenever uninstalling antivirus software, as there are registries and dependencies, installed deep within the OS which the traditional Control Panel uninstaller (appwiz.cpl) might miss in most cases.
If removing the antivirus fixes this error, you can now install the same antivirus again, or you can switch to an alternative software or better still stick to Windows native AV program – Windows Defender.
5] Rename/Clear the Windows Update cache
The Software Distribution folder in Windows operating system is a folder located in the Windows directory and used to temporarily store files that may be required to install Windows Update on your computer. This solution requires you clear the contents of the Software Distribution folder and then retry the update process again.
