Welcome to the UefiFirmwareSetup wiki! It is a good idea to reboot Windows into UEFI firmware setting, AKA "BIOS setup", while the UEFI booting speed is getting so fast that gives us a hard time to hit the POST hotkey for entering BIOS setup.
But it is kind of deep to access the feature in Windows 8/8.1/10 and too many user interaction than I expected : https://support.lenovo.com/us/en/documents/ht081446.
So I make this tool using Visual Studio 2008 Express to make a Win32 utility to utilize this UEFI 2.4 which is also supported by Windows 8 or newer. Check out description for "OsIndicationsSupported" & "OsIndications" in "7.5.4 Exchanging information between the OS and Firmware" for details.
