After this update “sfc /scannow” gets stuck at 100% for about 6-7 minutes, and afterwards reports that there are corrupted files that it cannot fix and asks for reboot.

The situation with “sfc/scannow” repeats after restart. I checked it with three different machines. There are a lot of errors in CBS.log file.

We’re aware of an issue impacting some Windows 8 customers trying to run the sfc /scannow command after installing KB2821895, where customers using the System File Checker receive an error message that there are corrupt files and that the system requires a restart to repair the files. 

To work around this issue:

·         Open an elevated command window

·         Run the command dism /online /cleanup-image /restorehealth, and wait for this command to complete.

·         Run the sfc /scannow command again until the command completes and reports that there is no corruption. If you still get an error that there is corruption, you should contact technical support for further assistance as your system may have actual corruption.

    Am having similar problems others described on Iconia W510 hybrid tablet purchased Nov 2012 from MS Store.  No big techie but ran sfc /scannow and saved sfc log. Then saw post on Dism restore health on EightForums but that failed. Kept CBS log which showed corrupt data. Need smaller Win8 footprint on my 32GB system even though allows micro SD cards. So finally ran complete system disk restore using Acer disks reloaded and reupdated except for 1895 KB. Ran sfc again and no integrity violations. Now even though have hidden KB... 1895 on update history, MS keeps offering it over and over again. Also my update history says I never installed any updates. I personally won't be doing any further updates until MS straightens this out. MS owes its users and early adopters of Windows 8 that much.

    Also went from having 1.84 GB of free space to having 9.8-something on C: drive after reinstall recovery, no insignificant change on my little tablet system.

     Be happy to upload logs if you all will tell me where. Can't be making this up 'cause I wouldn't know how.

     Updated 6-15. Immediate problems. Reinstalled June 16. Belive Acer may use same type of UEFI as poster above mentions on this tablet but not sure.

    If you look here http://support.microsoft.com/kb/2821895 you will see this:

    The installer in the Unified Extensible Firmware Interface (UEFI) firmware does not work correctly.

    I run under UEFI.  Can this be the problem? 

    Hi,

    First of all as we see from this thread, the problem is not connected with this update of UEFI installation.

    But, you are right, I have the same concern that this one is the most important update from the package regarding UEFI installation.

    MS, any definitive solution for this problem yet?. 

    Yes, my name says MSFT, but I'm not on the team that owns this...

    I have noticed this behavior too, but only because of this post.  The sfc error is known but the file is actually OK and I'm pretty sure spurious error can be ignored.  Are you having symptoms other than sfc not quite behaving as expected?  Is there a reason you ran sfc?  I'm not experiencing any other problems myself, so my "plan" is to ignore this on my machines.

    The high disk usage is because it's trying to compress files, which takes some time and thought, and should better prepare your machine for future updates.  After that one-time hit, there shouldn't be any performance issues.

    Hi, the sfc/scannow is one of the most important Microsoft tools to check the health of a machine. To ignore it means there is no possibility to resolve possible issues in the future or find out the source of the problem.

    Best Regards, Nicolator
