A bug persists on your PC, even when you turn it on again? Can't access Bios? Disable fast startup to force Windows to shut down and restart cleanly.
One of the great qualities of Windows 10 is its speed at launch: after turning on the computer, it only takes a few seconds to display the welcome screen, if you have an SSD, the process being a bit longer from a hard drive. A very appreciable speed, which one owes by a function of Windows activated by default: the fast start.
How does Windows Quick Start work?
The principle of fast startup is very simple: when you shut down your PC normally, Windows does not shut down entirely: it goes into a deep sleep - a hibernation, close to hibernation. The system closes all applications, open files and logs off users, but it automatically saves the state of the Windows kernel as well as the device drivers in a hibernation file (hiberfil.sys). This hidden file is most often stored at the root of the primary drive - the one where Windows is installed. When you restart your computer, Windows loads it instead of gradually booting the whole system, which can significantly speed up the system boot compared to a "cold" boot.
But while fast startup makes Windows launch faster, it also has a few drawbacks. If a device malfunctions, due to a bug in its driver, for example, the problem persists when Windows restarts. This is the case when the numeric keypad is found disabled on some PCs. then all you have to do is deactivate the fast start-up so that everything is back to normal. Quick start also regularly causes problems with dual or multi boot PCs, when multiple operating systems are installed. Indeed, this function locks the disk where Windows is installed, which blocks access to this disk from another OS. Similarly, on some PCs, fast startup can prevent access to the Bios or UEFI settings, which determine the "physical" settings of the computer. Finally, fast startup can also cause some problems with drives encrypted by an encryption solution like TrueCrypt.
For all of these reasons, it may be useful to turn off fast startup, if only temporarily. Knowing the launch of Windows will then take a little longer ...
