Issue: When I start Windows on my laptop, I receive the following error every time: “C:\Windows\system32\dxcore.dll is either not designed to run on Windows or it contains an error.” How can I fix it?

Solved Answer

Understanding DLL files and their errors in Windows

DLL (Dynamic Link Library) files are essential components in the Windows operating system, enabling multiple programs to share the same functionality and resources without redundancy. These files, which contain code and data used by various applications, are integral to the smooth operation of many Windows functions.

By allowing programs to use shared libraries of instructions, DLL files contribute to more efficient memory usage and overall system performance. However, despite their importance, DLL files can sometimes cause problems for various reasons, and one such problematic file is dxcore.dll.

Occasionally, when you start your PC, you might encounter the following error message:

C:\Windows\system32\dxcore.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

This message indicates that the dxcore.dll file, which plays a crucial role in the Windows operating system, is either corrupted or incompatible with your system.

What is dxcore.dll?

Dxcore.dll is a component associated with DXCore, an adapter enumeration API for graphics and compute devices, used by Direct3D 12. This API supports various tasks related to multimedia, particularly in handling graphics and compute devices, thereby overlapping with some facilities of DXGI (DirectX Graphics Infrastructure).

The primary function of dxcore.dll is to facilitate these multimedia tasks, ensuring that your system can handle complex graphical and computational processes efficiently. When this file is faulty, it can disrupt the normal operation of programs relying on Direct3D 12, leading to performance issues or preventing certain applications from running.
