14 DAY TRIAL // Microsoft has confirmed a problem with the MS13-057 Windows 7 Update earlier today, but it seems like this wasn’t the only buggy fix delivered on Patch Tuesday.
According to some posts on Microsoft’s support forums, the KB2821895 bulletin has broken down “sfc /scannow” on Windows 8 and the only way to deal with it is to completely remove the patch.
“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,” one user explained in a post.
A Microsoft support engineer has already replied to the bug report, saying that the company is now looking into the issue, suggesting that a fix could follow soon.
“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,” he wrote.
In case you’re not willing to completely delete the update using either a System Restore point or the built-in manual removal option, Microsoft recommends users to launch a command prompt window with administrator privileges and input the following command:
“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,” he noted.
