  • What do you do if it doesn’t come back without errors.

    Here is the actual screen dump info…

    Microsoft Windows [Version 6.2.9200]
    (c) 2012 Microsoft Corporation. All rights reserved.

    C:WIND0WSsystem32>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 some of them. Details are included in the CBS.Log windirLogsCBSCBS.log.
    For example C:WindowsLogsCBSCBS.log.
    Note that logging is currently not supported in offline servicing scenarios.


    When I tried to go to C:WindowsLogsCBSCBS.log using Command Prompt as Administrator then I get “Access is denied.” The same happened when I tried the string search: findstr /C:”[SR] Cannot repair member file” %windir%logscbscbs.log >c:sfcreport.txt

    Is there some way to do a system file check using the Windows 8 disk or refreshing the cache files?

    BTW SFC /purgechache doesn’t work with Windows 8.
