So I had this problem today. Well to be honest, I had this problem before as well but I decided to fix it today. Earlier today, I upgraded to Windows 8.1 and I was hoping that the upgrade would resolve this problem. Well, it didn’t. After surfing through the web, I found the solution. So, here it goes:
First of all, you need to be in safe mode. Open the charms bar, click on the power button, hold the
shift key and while you’re holding it, click
"Restart". This will restart Windows in troubleshooting/recovery mode.
