How to disable the Fast Startup feature on Windows

To partially overcome the slow system startup of Windows computers, Microsoft has introduced a feature called 'Fast Startup'. Fast Startup helps reduce Windows computer startup time significantly, but can also prevent the system from actually shutting down completely. Learn more about this issue below.

Fast Startup - a form of putting the system to 'sleep'

Normally, you don't need to shut down your PC anytime it's not in use. Sleep mode (Sleep or Hibernation) can put your PC into a low-power state so it can quickly reboot whenever you need to keep working.

When not using the computer for a long time, you may want to shut down the system completely. This forces your Windows 10 or Windows 11 PC to completely reload on the next boot.

With a feature called Fast Startup, which was introduced first in Windows 8 and is still present in Windows 10 and Windows 11, many PCs that support hibernation are only really brought back to the same state. like hibernate when off. At that time, the operating system state (in RAM) will be saved to a file named hiberfil.sys. This allows Windows to quickly reload when you next start your PC.

It can be said that TFast Startup is a combination of hibernation mode (Hibernate) and shutdown process (Shutdown), helping the system to significantly reduce startup time. In simple terms, Windows PC will not be able to shut down completely when the 'Fast Startup' feature is enabled.
