Hello,
I was having the same problem as @ NikhilKolhapuri I followed all of the steps above and completed the repair install, however, I still get "There are currently no power options available." The only way I can do a complete shutdown of my computer is to Ctrl+Alt+Delete, Lock, then access the power options from there. This problem started after I had to download Respondus Lockdown Browser for school. I uninstalled it as soon as I was able to, but continue to have the problem despite multiple attempts to resolve it.
