We’ve personally experienced this problem ourselves. As How-To Geek notes, a standard shut down might not be enough to get Windows to stop freaking out during these fun moments: However, there are times when you might want to shut down your system the real way – if you’re having an odd issue with Windows, for example. Depending on your system configuration, it can do a good job of getting you back into the operating system nice and fast when you “power up” your PC. There’s nothing wrong with Windows 10’s fast startup feature. The speed boost comes from the Windows kernel being saved on your hard drive and loaded when booting. Why? You’re logged off before the file is created, meaning your session is not recorded. A hibernation file is indeed used, although it is smaller than usual. With fast startup enabled, choosing to shut down your PC might look like you’re completely shutting things down, but in reality, your PC is entering a mix between a shutdown and hibernation. What you’re actually doing when you shut down your computer is putting it into a hybrid state, the “ fast startup” feature enabled by default in Windows 10’s settings. This is an older Windows 10 quirk, but one worth highlighting every now and then in case you forgot that “shut down” isn’t really “shut down”.
