Vulkan Run Time Libraries 1.0.39.1 <HOT — 2026>

Vulkan Run Time Libraries 1.0.39.1 is an obsolete, safe, and small graphics API runtime from 2016. It is no longer required on any up-to-date Windows system because modern GPU drivers include far newer Vulkan versions. Uninstalling it leaves full Vulkan support intact (via the driver’s own runtime). Its presence indicates an older software installer or driver component that can be cleaned up.

Here’s a short, informative piece on Vulkan Run Time Libraries 1.0.39.1:

What Is Vulkan Run Time Libraries 1.0.39.1?

If you’ve spotted Vulkan Run Time Libraries in your Windows installed programs list, specifically version 1.0.39.1, you might wonder if it’s necessary—or even safe.

The short answer: Yes, keep it.

What it is:
Vulkan is a modern, low-overhead graphics API (like DirectX or OpenGL), developed by the Khronos Group. It allows game developers and 3D applications to talk directly to your GPU for better performance. The “Run Time Libraries” are the system files that let Vulkan-based apps run on your PC. vulkan run time libraries 1.0.39.1

Version 1.0.39.1 is an older but stable release from around late 2016–early 2017. It typically gets installed automatically by:

Do you need it?
If you play modern PC games or use 3D software, yes. Without it, Vulkan-based games won’t launch or will fall back to slower graphics APIs. The libraries take very little space (tens of MB) and run only when called by an app.

Is it a virus or bloatware?
No. Some users mistake it for malware because the name sounds technical, but it’s a legitimate component. However, if you uninstall it, your graphics driver may reinstall it automatically—or worse, break Vulkan support in apps.

Should you update it?
Version 1.0.39.1 is quite old. The best way to update is to install the latest graphics drivers from NVIDIA, AMD, or Intel. They ship with newer Vulkan Run Time Libraries (e.g., 1.3.x or later). Never download “standalone updates” from random sites—only through official driver packages.

Bottom line:
Leave it alone unless you’re absolutely sure no Vulkan software runs on your PC. If you see version 1.0.39.1 and want the latest features or bug fixes, update your GPU drivers. Otherwise, it’s just quietly doing its job in the background.

You have this entry for one of three reasons: Vulkan Run Time Libraries 1

Vulkan Run Time Libraries (often shown in system software lists as "Vulkan Run Time Libraries" or "VulkanRT") are components that implement the Vulkan graphics and compute API on Windows systems. Version 1.0.39.1 is a specific release in the Vulkan 1.0.x series. Below is a concise, useful overview covering what it is, why it appears on systems, compatibility, installation, troubleshooting, and security considerations.

After updating, you can uninstall the standalone 1.0.39.1 entry – the newer version will handle all Vulkan calls.

If you’ve recently glanced at your list of installed programs on Windows, you might have spotted an entry labeled “Vulkan Run Time Libraries 1.0.39.1” and wondered: Where did this come from? Is it a virus? Do I need it?

You are not alone. This specific version – 1.0.39.1 – appears on millions of gaming PCs, often installed silently alongside graphics drivers or modern video games. In this deep-dive article, we will explore everything you need to know about the Vulkan Run Time Libraries, with a specific focus on version 1.0.39.1, its purpose, its safety, and whether you should keep or remove it.

Before understanding the libraries, you need to understand Vulkan. Vulkan is a low-overhead, cross-platform 3D graphics and compute API (Application Programming Interface) developed by the Khronos Group. It was designed to be a modern successor to OpenGL, offering developers much more direct control over GPU hardware.

Key features of Vulkan include:

The Vulkan Run Time Libraries are the essential system files (DLLs, loaders, and layers) that allow Vulkan-enabled applications to communicate with your graphics card.

Vulkan is a modern, high-performance cross-platform graphics and compute API (Application Programming Interface). It is similar to OpenGL or Microsoft’s DirectX 12. It allows games and applications to communicate directly with your computer's graphics hardware (GPU) for maximum efficiency.

The "Run Time Libraries" are the files required to run software built with Vulkan. The version number 1.0.39.1 indicates the specific build of the runtime installed on your system. This is an early, stable version of the API, released around mid-2016.
