Open your web browser and go to Microsoft’s official DirectX download page. Be extremely wary of third-party sites promising “DirectX 12 offline installer 2024/2025.” These are often bundled with adware, toolbars, or malware. Always use microsoft.com domains.

For most users, the easiest way to keep DirectX 12 up to date is simply to run regularly. Microsoft delivers DirectX 12 updates as part of the Quality Updates and Feature Updates for Windows 10 and 11. These updates include new shader models, the DirectX 12 Agility SDK, and performance improvements.

Wait 30–60 seconds. When finished, you will see: "DirectX Setup has completed successfully." Restart your computer.
