Cannot install KB3079777 MS Update - Error 80070570 - Windows 8.1

[xcooper]

Unable to install MS Update KB3079777 on Windows 8.1 Toshiba Satelite Pro Laptop with MS error: 80070570. Saw mention of using sfc /scannow from cmd prompt as Administrator - Fixes something but still unable to install updates. Tried again using link from sfcfix.exe from sysnative, does pretty much the same thing in DISM except easier to locate log files and save. Don't fully understand all this other than following instructions, but do have the cbs.log and SFCFix.txt (zipped - CBS.zip) log files - please find those attached if that helps? Would appreciate any assistance as this not my domain....thank you. Chris

Sorry, meant: CBS.log is zipped as CBS.zip (as was 7mb approx.) and SFCFix.txt is just that.....happy to provide any further information/data/log files required to assist. Kind regards. Chris

Hi xcooper :)

My name is Aura and I'll be assisting you with your issue. Follow the instructions below please.

System File Checker (SFC)
Follow the instructions below to run a SFC scan on your system and to provide the CBS log in your next reply;

• On Windows Vista & 7, click on the Windows Start Menu, then enter cmd in the search box, right-click on the cmd icon and select
  
  Run as Administrator
• On Windows 8, drag your cursor in the bottom-left corner, and right-click on the metro menu preview, then select Command Prompt (Admin);
• On Windows 8.1, right click on the Windows logo in the bottom-left corner and select Command Prompt (Admin);
• Enter the command below and press on Enter;
  

  sfc /scannow

  Note: There's a space between "sfc" and "/scannow";
• Once the scan is complete, enter the command below and press on Enter
  

  copy %windir%\logs\cbs\cbs.log "%userprofile%\Desktop\cbs.txt"

• A file called cbs.txt will have appeared on your Desktop. Upload the file on Dropbox, Google Drive or OneDrive and post the download URL for it here;

Note: Please note that the CBS.log is volatile, which means that if you don't upload it after the SFC scan is completed, it won't contains the information from the scan anymore. So archive it and upload it as soon as you can.
