Note: Fast Startup is designed to make your PC boot faster but may interfere with accessing BIOS or dual-boot configurations. Disabling it fully shuts down the PC without saving system state. The Fast Startup feature is only applicable to shutdown, not restart. These instructions are verified and work for Windows 11 as of 2025.
