MSI Fast Boot also adds a background controller service designed to run automatically post-installation. You can delay the start of this service using the service manager.

How MSI Fast Boot Works

UEFI fast boot comes with two modes, including enabled mode or normal mode and the fast mode. When running the normal mode, UEFI skips some startup checks and boots your PC faster. When running the fast mode of UEFI fast boot, it skips the entire POST screen where you can enter UEFI firmware with a hotkey. This prevents you from entering the UEFI firmware as you never get the option to press the hotkey.

MSI Fast Boot app allows you to reboot into UEFI Firmware directly from Windows even if you have fast mode enabled. Most users don’t know, but you can enter UEFI firmware even without the utility app by simply pressing & holding the left Shift key and restarting your PC.
