Fast Startup in Windows 11: When should you turn it off and how?

How Fast Startups work: Benefits and trade-offs

Fast Startup is a built-in feature in Windows 11 and Windows 10, designed to shorten computer boot times. This mechanism works by combining hibernation and a complete shutdown. When you shut down your computer, the system saves the operating system kernel, drivers, and system state to a hibernation file (hiberfil.sys), allowing the computer to restart faster from this saved state.

However, this convenience comes with some potential drawbacks. Fast Startup can conflict with the Windows update installation process, complicate the management of encrypted storage devices, and cause problems in dual-boot systems due to restricted access to drives from the other operating system. In some cases, this feature even prevents users from accessing the motherboard's UEFI (BIOS) settings.
