KB2821895 Windows 8 x64 Update 06.11.2013 problem

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.

    Hi,

    Same Problem with KB2821895 for me on Win8 x86

    I discovered it to be problematic when I ran cleanmgr.exe afterwards, which took nearly 2 hours under 100 % CPU Usage.

    Thereafter got same problems with System File Checker reported by the others here.

    Also strange:

    After Update & running cleanmgr.exe, there is a huge "Reserve.tmp"-file in Windows/WinSxs, about 2 Gigs on my system, other folks in german forums report the same with different sizes from ca. 100 MB to > 3 Gigs. 

    Q:

    1. Is the running of DISM a real fix for that or just a sketchy solution ?

    ( Folks in german forums have compared their system files with the file list of the updated dll's in http://support.microsoft.com/kb/2821895 and came to the conclusion, that the update seems to be not properly installed )

    1. Can I delete the "Reserve.tmp"-file in WinSxs ?
    2. Would you recommend to go back to a complete System Backup before the patchday ( I made one right before the updates )  and install all updates excluding  KB2821895 ?

    After I ran system file checker and did the restart, at the Restarting message screen,  it said something about one something was pending, pauses a moment then restarted.    I did sfc twice and at both of their restarts that same pending something delayed the restart a moment.    I assume it was the offending KB# tying to finish installing.   

     

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

    zipped and uploaded one to here;   http://sdrv.ms/12FXRd3  Very large but zipps to 3mb

     

    Dism is supposed to use Windows Update server for files it needs.   After that 2nd sfc failure I ran the DISM's and saw no pending something at the next Restart.   So I assume it fixed it correctly.

    Hi,

    I can confirm I have the same problem as others had explained. I'm using Windows 8 Pro x64 and did a fresh install. All windows updates are working except KB2821895. I no longer have the cbs.log file cause I've done a system restore. The Dism method as mentioned might fix it but I'm still waiting for Microsoft to fix the update/patch and an official answer.

    Considering other non - techie users who applied the KB2821895 might not noticed anything wrong until they do "sfc /scannow" in command prompt, I feel like this update is not working as intended. But, hopefully we can get an official answer /fix from Microsoft soon. Until then, best i can do is hide the update and create a restore point / disk image.

    Thanks, Best of luck

    BTW have tried the:

     sfc/scannow 

    ◦DISM.exe /Online /Cleanup-image /Scanhealth

    ◦DISM.exe /Online /Cleanup-image /Restorehealth

    plus several different attempts at different System Restore points

    all to no avail.

    Thanks
