    Windows 10 opencl.dll Error

    After past days, this week i've discovered another problem with windows...

    Everyoen know that Windows 10 x64 and latest geforce forceware drivers are giving problems... in fact 355.60 WHQL release was bugged as hell and give a lot of problems, like VIDEO_MEMORY_MANAGEMENT_INTERNAL BSOD.

    Today nvidia realeased a beta drivers to fix that issue...

    355.78 (It provides a bug fix for an intermittent issue found in the publicly released 355.60 Game Ready driver as well as solving an issue with incorrect display timings. )

    64-bit: http://developer.download.nvidia.com...ernational.exe
    32-bit: http://developer.download.nvidia.com...ernational.exe

    but seems problems are related to
    Windows 10: Memory Compression

    well... running usual

    sfc /scannow

    i've picked up another bad error:

    [2015-08-25 01:05:19, Info                  CSI    00003cc6 [SR] Beginning Verify and Repair transaction

    Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:O:\sources\install.wim:1 /limitaccess

    did NOT fixed the error since it's related to nvidia drivers.

    So i digget into it and discovered opencl.dll into C:\WINDOWS\WinSxS\wow64_microsoft-windows-r..xwddmdriver-wow64-c_31bf3856ad364e35_10.0.10525.0_none_3dede48956615b25 it's OLD, compared to the one found inside C:\NVIDIA\DisplayDriver\355.78\Win10_64\International\Display.Driver\opencl64.dl_

    So i've took over WinSxS file and replaced with the one found into nvidia folder.. BUT... i STILL get error into CBS.log.

    What now?

    It is Microsoft vs. Nvidia conflict. Ask Microsoft to remove wow64_microsoft-windows-r..xwddmdriver-wow64-c_31bf3856ad364e35_10.0.10525.0_none_3dede48956615b25
    opencl.dll installed as hardlink to WinSxS and then NVidia installer overwrite both of them at once, so WinSxS hash is lost and sfc can't restore old file.
