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.

    Okay, I did sfc /scannow and it said some files couldn't be repaired like 15 minutes after the verification was 100%. So I rebooted and I'm running the command. Microsoft needs to get their act together for these updates. Seriously, I'm tempted to go back to Windows 7.

     

    dism /online /cleanup-image /restorehealth

     

    How long should this take? Its been at 20.0% for a while and it just went to 40%.

    I'm sorry that you're having to go through this, CannedBullets, too, as a consumer of 

    MS Windows 8. I agree that this is extremely frustrating, especially when the apparent

    "experts" in this community appear to be snobbishly concluding that it's the consumer's

    fault that we are having trouble with Microsoft's Windows 8 updates. Wish they could see

    our records of carefully updating and virus checking our Windows 8 computers to

    prevent issues. IT's MS UNTESTED UPDATES THAT IS THE ISSUE would be my reply.

    I've now done sfc check and restore health check so many times I can't remember how

    long it takes when. But as I recall, sfc checker takes quite a bit of time (as in over a half

    hour) to repair the update's system damage, and resto (re health can take a while (something

    just a little shorter perhaps) to finish repairing files. I believe some of the early posters

    in this thread reported times of over an hour. Just let sfc file checker and restore health

    run until completed. Once started, I believe it is very unwise to stop either process.

    As a non-techie consumer, not sure just why. Perhaps the experts could weigh in on

    times required.

    Personally since system damage inflicted by 2821895 on June 15, I've spent three 8 hour

    days (at least) correcting and restoring my Windows 8 system. MS does need to be

    more careful with their update work (and perhaps OS design) - I agree. Long, cold

    day before I'll jump in on a new product again. And I've been with MS since 3.1 Almost

    pre-ordered SurfacePro. That's not going to happen.

    Have now been able to repair my system with the restorehealth online, too.

    Used local computer guy, who said be sure your system passes sfc /scannow and DISM /online /cleanup-image /restorehealth before you even try and install KB2821895

    Worked. Update installed. took about 30 minutes to complete sfc /scannow. Another 10 to run

    DISM /online /cleanup-image /restore health after the update installed.

    Removed dropbox file of log links. So that won't work any more.

    fyi, although no seems to be reading posts, initially my computer after 2821895 install had  13.2 GB of free space.

    Then made the mistake of running disk cleanup to get rid of 477 MB of update files cleanup. Four hours later, and left on overnight, which also ran a scheduled disk defrag and optimization after cleanup finished, my system only had 11.7 GB of available free space.

    Perhaps this update should come with the caveat run scannow and DISM-restore health before

    installing? Seemed to do the trick after really messing up my system on June 15. But I won't be

    a particularly happy Microsoft consumer if I have to keep hiring an IT guy to do Microsoft Win8

    updates. Now know to wait, wait to update and let other guinea pigs do it first. And also know

    not to use the current Windows 8 disk cleanup, too.

    Thanks for the hints in right direction.
