After Windows 10 Update 1511 – better known as Windows 10 November Update or Threshold 2 – was released late last year, many people complained about a corrupt opencl.dll file. After further investigation and discussion on the Windows 10 forums, it was determined that it was a fairly common problem, but not a particularly serious one, as a corrupt opencl.dll file does not negatively affect the computer or its graphical functions.

It was also found that this issue only affects Windows 10 users with NVIDIA GPUs. When an NVIDIA GPU user installs or updates NVIDIA drivers for their graphics card, either through NVIDIA GeForce or Windows Update, the NVIDIA driver installer automatically overwrites the existing Windows opencl.dll file with its own and corrupts it accordingly. Until NVIDIA fixes this problem, it will happen every time you install or update NVIDIA drivers.

Fortunately, you can determine if your computer’s opencl.dll file is corrupt and then repair/replace it to fix the problem. Even if a corrupted opencl.dll file doesn’t interfere with your computer’s daily operation, prevention is better than cure.
