Windows 10 corrupt files issue error 0x800f081f

The opencl.dll repair issue is strange. The user Daniel explained how he solved it on serverfault.com:

1. Mount the ISO image.
2. Create a temporary directory to mount the Windows Image File (WIM). mkdir C:\WIM
3. Mount the WIM file. Dism /Mount-Wim /WimFile:D:\sources\install.wim /index:1 /MountDir:C:\WIM /ReadOnly
4. Run Dism with the following parameters. Dism /Online /Cleanup-Image /RestoreHealth /Source:C:\WIM\Windows /LimitAccess
5. When done, unmount the image and delete the folder Dism /Unmount-Wim /MountDir:C:\WIM /Discard rmdir C:\WIM
6. It's mandatory to restart your computer, or SFC and DISM will still show errors.

You need a 10.0.10586 ISO from here.
