Ever experienced computer being stuck at 15% update screen forever when you've recently a Windows update? (I'm using Windows 7 64-bit - Update done on 11/2/16)
Things to do:
1) Unplug everything from your laptop (except your battery of course)
eg: Mouse, any USB, and charger.
2) Hold the power button and turn off your laptop.
3) Remove the battery from your laptop.
4) Insert the battery back to your laptop and restart your computer.
5) They should prompt these (Launch Startup Repair or Start Windows Normally) - Select Start Windows Normally.
6) When starting, a message should prompt,"Windows Failed to Update. Reverting Changes. Pls do not turn off your PC".
7) After this, your laptop will work normally.
This method works for me. Hope it works for you too. All the best :)
