I had a problem with Windows 10 shutting down so I checked the Microsoft Community ,there I tried the solution of turning off fast start-up/disabling hybrid shutdown and it worked.
As this was Introduced in Windows 8.1 ,before migrating to Windows 10 there wasn't any problem unlike now after the Migration.So why did this not cause any problem in earlier windows 8.1 was this option disabled by default or it had some other settings.
Also what exactly is Hybrid shutdown and in which scenario is this useful
