Hi Zehel :)

My name is Aura and I'll be assisting you with your issue. Since this is the Windows Update section, I can only assist you with issues related to that domain. For the others, once I'm done with you, I'll redirect you in the proper section, alright? 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 have the information from the scan anymore. So archive it and upload it as soon as you can.
