In case you are using an older version of the conflicting software on your computer, you would need to update it to its latest version before attempting to apply updates to Windows 10. You can do that by visiting the official website or distribution sources of that software or just use the Check for updates feature of that software only if it is available.

2] Uninstall the conflicting software

The best action you can take is to get rid of the conflicting software.

Uninstall a program from Windows 10

You can either uninstall it using the built-in uninstaller on Windows 10 or can use uninstallers from third-party developers like Revo Uninstaller and more.

Make sure to backup all the user data of the software, if there is an option. Some game software saves game progress in a different folder, and saving them would be worth your time.

All the best!
