I recently got the Anniversary Update for Windows 10 and it was working fine for a while, but now whenever I try to use the shut down option from the Start menu it doesn't do anything at all (as in no action happens, no logout and no black screen), I have to force shutdown by holding the power button. I tried to refresh my PC but even that doesn't work from settings, and booting into advanced startup and trying to refresh my PC from there also doesn't work (because holding shift and pressing restart also doesn't do anything). The Sleep option works, however.
I ran sfc /scannow
as admin on command prompt but it returned that there were no errors
