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.

    Got the same results as you did I think

     

    6-21 snipping tool shot and CBS and DISM logs are now at this link, too:

    https://www.dropbox.com/sh/us3boba6essu21b/JMKQ7gA_Kj

     

    Both commands completed. Scanhealth took about 4 minutes and found

    no store corruption. Restorehealth command took about 10 minutes (total 32GB SSD

    about 20GB occupied) and says it successfully repaired corruption.

     

    So where are we now?

    Obviously the 2821895 update caused some problems, at least for my Acer W510 tablet.

     

    Not installing this update has left me with a clean or at least repairable system.

     

    Is there any chance, Microsoft, that I will be able to use Windows 8 because its footprint

    can be successfully reduced for a 32 GB mobile device, or at least this Acer W510?

     

    That's still my question. You sold me Acer's device and the keyboard dock through your

    MS Store. Hope I get to use it. Purchased tablet in November 2012 and keyboard dock in June

    2013 just before patch Tuesday. Would like to continue forays to Starbucks for news, books,

    and other computer activities. Thanks.

     

     

     

    If you run sfc /scannow, does it report any corruption?

    No. Ran sfc scannow twice with restarts inbetween. No integrity violations either time

    Found this gem of a  tip on the eightforums.com in a tutorial on using scannow. Unfortunately,

    didn't note the URL while I was copying. This text code does work and will extract info from your

    CBS log on corruption repairs by sfc:

    How to See and Read Only the "SFC" Scan Results from the CBS.LOG

    NOTE: When SFC runs, it logs it's actions into the C:\Windows\Logs\CBS\CBS.log. The steps in this option will

    show you how to see only the specific SFC entries with the [SR] tags in this CBS.log. This can be helpful to

    show you what files SFC could not fix automatically if you wanted to try and manually replace them.

    1. Open an elevated command prompt in Windows 8.
    2. In the elevated command prompt, copy and paste the command below and press Enter.

    NOTE: This will place a sfcdetails.txt file on your desktop with only the SFC scan result details from the

    CBS.LOG in it.

    Code:

    findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >%userprofile%\Desktop\sfcdetails.txt

    1. Close the elevated command prompt.
    2. Open the sfcdetails.txt file on your desktop to see the SFC scan details in the CBS.LOG.
    3. When finished, you can safely delete the sfcdetails.txt file afterwards if you like.

    Tip

    The import of the tutorial also stated that one runs sfc /scannow first until you get your

    integrity violations fixed. May take up to three attempts with restarts inbetween.

    Then if scannow can't fix it, run DISM /Online /Cleanup-image /Restorehealth and see if

    that will cleanup store corruption.

    Is that other people's understanding, that the proper order is run sfc /scannow first and then

    if that does not work, DISM?

    Thanks.

    Are there any results to update on Microsoft KB2821895 and whether or not it is

    safe to use?

    Is the only proposed solution:

    update KB2821895

    run sfc /scannow

    if indicates corruption, run: DISM /online /cleanup-image /restorehealth

    and hope that works?

    That's all for those of us who have had issues with the update?

    Thanks

    The problem with the upgrade mentioned has been confirmed.  But since the message below appears on two systems with the problem, it would seem to be highly unlikely all those components became corrupted overnight.  It would seem more likely the information/database the SFC uses to check the files was altered in some manner. 

    I have repaired my system with the /RestoreHealth switch, so this post is basically just info.

    From extracted SFC log:

    "[SR] Committing transaction

    [SR] Cannot commit interactively, there are boot critical components being repaired

    [SR] Repairing 11474 (0x0000000000002cd2) components"
