Version 1.0.39.1 was released back in early 2017. This was a pivotal moment for Vulkan. At the time:
This specific build (1.0.39.1) was often bundled with:
This version is not installed standalone by an end user. Instead, it is bundled with:
During driver or game setup, the Vulkan runtime is placed in the system Program Files (x86) folder and registered via an MSI installer.
Yes. Vulkan Run Time Libraries 1.0.39.1 typically installs both:
The Vulkan Run Time Libraries provide the necessary runtime components for applications and games to utilize the Vulkan graphics API – a low-overhead, cross-platform 3D graphics and compute API. Version 1.0.39.1 is an early maintenance release of the Vulkan 1.0 specification.
Key functions:
Vulkan Run Time Libraries 1.0.39.1 is a legitimate, safe graphics component required for many games to run. It was likely installed by a game or a graphics driver update. It is not bloatware; it is a tool that helps your hardware run faster and more efficiently. You should leave it installed. vulkan run time libraries 1.0.39.1
Vulkan Run Time Libraries 1.0.39.1 is a legitimate graphics application programming interface (API) component often found on Windows PCs. It is not a virus or malware; rather, it is a piece of essential software that helps your computer handle high-performance 3D graphics for gaming and professional applications. What is Vulkan Run Time Libraries 1.0.39.1?
The Vulkan Run Time Libraries (VulkanRT) are cross-platform graphics and compute APIs developed by the Khronos Group. Version 1.0.39.1 is a specific release of the "loader" that allows your operating system and applications to communicate directly with your Graphics Processing Unit (GPU).
Unlike older standards like OpenGL or DirectX 11, Vulkan is designed to be "low-overhead." This means it gives software more direct control over the hardware, leading to:
Lower CPU Usage: By reducing driver overhead, your processor spends less time managing the graphics card.
Better Multi-core Scaling: It can distribute workloads more evenly across modern multi-core processors.
Increased Performance: In compatible games like Dota 2, Doom, or Star Citizen, it can provide higher frame rates and smoother gameplay. How Did It Get on Your Computer? Vulkan Runtime and Loader Security on Windows OS
Here’s a short, informative piece on Vulkan Run Time Libraries 1.0.39.1: Version 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.
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. This specific build ( 1
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.
Important: If you uninstall 1.0.39.1 and a program requires it, that program will either (a) prompt you to reinstall, (b) crash, or (c) fall back to a different renderer (e.g., OpenGL or DirectX). Uninstalling is generally safe but not recommended for gamers.
Absolutely not. This is a legitimate, signed system component from The Khronos Group Inc. However, malware sometimes uses similar sounding names to hide. To verify your copy is genuine:

Spoiler: For millions of users, this file is 100% safe.
It depends. Both offer low-level GPU access. Vulkan is more portable; DirectX 12 is more common on Xbox and Windows. Many developers consider Vulkan easier to debug.
