I am running Windows 8.1 Pro WMC

I Found KB2938527 in windows update and it downloded perfectly. But when i installed it showed errors: WindowsUpdate_80073712 and WindowsUpdate_dt000.

When I ran sfc /scannow the I get the following output

Code:



C:\Windows\system32>sfc /scannow
Beginning system scan.  
This process will take some time.Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files but was unable to fix someof them.

I also tried DISM to restore health but it also fails. Here is the output

Code:
C:\Windows\system32>dism /online /cleanup-image /restorehealth
