How to enable or disable fast startup on Windows 11

On Windows 11, “Fast Startup” is a feature that speeds up the startup process. The feature has been available in previous versions of Windows, and it combines the hibernation and shutdown power techniques to boot a device faster than the traditional process. 

If you want to understand how the fast startup feature works, you first need to understand hibernation. On Windows 11, when you enable “Hibernate,” the system saves the current session loaded into memory to the hard drive, allowing you to pick up where you left off quickly, even in the event of power loss. The same idea is how “Fast Startup” works, but instead of saving everything loaded into memory, Windows 11 first signs off any account and then saves the memory’s content onto the hard drive. As a result of this technique, the system can start more quickly since many services and applications are simply restored from the last session.
