Access UEFI firmware settings using Windows 10
On Windows 10 PCs you can access UEFI Firmware Settings through the operating system. In UEFI it is possible for the OS to call back into the firmware in a standards-compliant way. Windows takes advantage of this functionality. You no longer need to remember some special keystroke which varied from motherboard to motherboard and press it just at the right time while your PC is booting in order to access the firmware settings.
