    Have you tried searching for solutions yet, or just wanting us to walk you through the easy steps to fix this issue. Your problem is not with Windows 10, it is with your Video Chipset driver.

    Opencl.dll hash mismatch is a known problem with Nvidia drivers. See the SFC command tutorial here SFC Command - Run in Windows 10 - Page 12 - Windows 10 Forums . The advice has been to ignore it when running the SFC command.

    Again your problem is not with SFC or Windows. It is with OpenCL.dll which is caused by the Video Drivers. Try using the correct search, instead of the command that gave you the error.

    Just a little NEW information on the Opencl.dll issue's After downloading the latest drivers from Nvidia few days ago, Version 361.91
    Then running sfc /scannow after installing the latest drivers, for the 1st time in the last 4 months, sfc found NO ERRORS!! Then I went and looked at my Opencl.dll drivers and location of them. Nvidia has changed how they install and where they place their drivers in this latest update. They do not replace the MS Opencl drivers like they did in the past with their updates, so looks like Nvidia has fixed the problem with Opencl errors .... at least for THIS latest update. I was VERY surprised to see this, as I kept thinking it was a problem from MS, not Nvidia.

    Just thought I would post my results on the Opencl.dll errors that lots of us USED to get ... Until THIS new update.

    Everyone has known about the opencl-dll problem since 7, because it has been mainly with NVidia. When 10 came out, NVidia was late on putting the latest drivers in Microsoft's repository, so Microsoft used the drivers from Windows 8.1, until NVidia released updated the drivers aprox. 2 weeks after 10 was released out to the wild in Aug.

    That's not correct as Windows 7 did not have issues with Nvidia drivers. Windows 10 the early version 10240 also had no problems with Nvidia drivers. I ran both versions on 2 computers, never had problems with any Nvidia drivers, until the release of Windows 1511, then lots of people starting have problems with any Nvidia driver, or updates. Until this latest release of 361.91 just recently.

    Not to argue, but it is correct. You will find a lot of Linux posts about the NVidia driver issues, same as some people were having issues with 7. It was more of a smaller percentage then what happened with 10.

    Yes I did hear of Linux having issues with Nvidia cards, which was a Linux issue, not Nvidia's . Also heard Linux fixed this issue a while back......not just recently. But this being more of a Windows forum then Linux, we never discussed it as much in here. Windows 7 never had any issue with Nvidia drivers, as I ran it for a long time on both computers. Actually still got a 3rd computer with Windows 7 still installed, but I don't use that one anymore, its stored and offline. All my versions of Windows 7 was either Pro or Ultimate versions.
