Windows 10 may be the new edition of Microsoft Windows OS and comes with plenty of improvements over the previous version. One of the highlights of the OS may be the customization support available. You can download countless themes from Microsoft to customize your desktop. Windows 10 themes download options are available in the Windows store as well. You can install themes that are provided by Microsoft or you can create them. But you cannot directly install custom themes as you need to patch system files before applying third-party themes.

If you desire to use third-party custom themes created by various developers you will need to patch certain system files in Windows 10.
