I had a similar problem on a Yoga 3 Pro and no matter what I did, it did not work. So I tried a tool that I have had other people run as a malware repair, and it fixed it right up. But I did not write down what the error was. I do not know if this will fix your problem.
The tool is called Windows Repair (All In One) If you want to give it a try, the instructions are below.
Download Portable Windows Repair (all in one) from one of the following:
http://www.tweaking.com/content/page/windows_repai​r_all_in_one.html
http://www.majorgeeks.com/Tweaking.com_-_Windows_R​epair_Portable_d7222.html

Unzip the contents into a newly created folder on your desktop. Make sure your AV protection is turned OFF before running the tool....
Open the folder, run the tool by right click on Repair_Windows (icon with red briefcase) select "Run as Administrator"
From the main GUI do the following:
Select Tab 3 and allow it to run Disk check
Select Tab 4 and allow it to run SFC
Select Tab 5 and Create System Restore Point
Select Start Repairs tab => Click the Start
The repairs window will open, uncheck the boxes as indicated, also the "Restart" option, then select Start...
DON'T use the computer while each scan is in progress.
