I had the same problem. I followed up Carlos instructions and rebooted.
Now, the following happened. My keyboard has stoped working. I had to
use visual keyboard to be able to loging my pc. So, I went back to
regedit and changed back the value to what it was (1). I rebooted and
then the keyboard started working and windows started charging properly.
Both of my problems are now solved.
