Help and Support does nothing

That's odd, I'm not seeing any errors in your CBS log at all. Can you download and install the System Update Readiness Tool please?

Download System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [May 2014] from Official Microsoft Download Center

Then run SFC again:

SFC Scan

1. Click on the Start button and in the search box, type Command Prompt
2. When you see Command Prompt on the list, right-click on it and select Run as administrator
3. When command prompt opens, copy and paste the following commands into it, press enter after each
   
   sfc /scannow
   
   Wait for this to finish before you continue
   
   copy %windir%\logs\cbs\cbs.log "%userprofile%\Desktop\cbs.txt"
   copy %windir%\logs\cbs\CheckSUR.persist.log "%userprofile%\Desktop\surt.txt"
   
   
4. This will create two files, cbs.txt and surt.txt on your Desktop. Please attach these to your next post.

Are you sure SFC is detecting errors? There's no problems at all in your log

Can you take a screenshot of what SFC says when it finishes please? Attach this to your next post.

I suggest running a repair install

Repair Install

You will not lose any programs or files. Still should make a backup before doing so however.
