WIndows 8 system file checker

I am having a few issues with Windows 8 regarding OS operating system files. I ran SFC /scannow and was looking at the CBS.LOG file. I am wondering where I can help in determining the issues noted in the log file. Here is an example of one of the issues reported:

****2013-10-17 16:20:23, Info CSI 00000081 Ignoring duplicate ownership for directory [l:92{46}]"\??\C:\ProgramData\regid.1991-06.com.microsoft" in component Microsoft-Windows-Branding-Base-Core, Version = 6.2.9200.16384, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral

2013-10-17 16:20:23, Info CSI 00000082 [DIRSD OWNER WARNING] Directory [ml:520{260},l:64{32}]"\??\C:\Windows\System32\Bthprops" is not owned but specifies SDDL in component Microsoft-Windows-BTH-CPL, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral****

SFC indicated that repairs could not be made.

In Windows 8 there is a better tool included. It is called DISM, which was created in Windows 7, but it was updated in Windows 8.

Here run the command DISM /Online /Cleanup-Image /RestoreHealth to detect and repair corrupted files. DISM also download corrupted files, which sfc doesn't do.
