Well the problem was with the ReFS Pack Enable Tweak. This ReFS Enable Tweak breaks the DISM /Online Servicing Function. Code: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MiniNT] "AllowRefsFormatOverNonmirrorVolume"=dword:00000001
@Komm or abbodi1406, Latest KUC wants to install KB2901101 to satisfy M$ update (superseeded by KB2908387); it is not required and can be eliminated completely if my experience is universal. The update cleanup completely removes it and if not installed M$ update does not ask for it, but, KUC flags it as necessary. This is my experience on Windows 8.1 Pro x64. Thanks
