Note: Cannot repair member files "win32k.ptxml" and "Amd64\CNBJ2530.DPB" which are the corrupted files.
I then ran SFCFix.exe and used my Windows 8.1 install DVD when prompted by the program.
SFCFix.txt (log) is below:

It looks like everything was repaired but if I delete CBS.log and run sfc again, I get listed the same 2 corrupted files listed.
I am at a loss in explaining this. Help.
