Check if Windows 10 is using UEFI or Legacy BIOS  

I created a .bat file using that code that works in a Command Prompt. I put it in Documents then Sent it to the Desktop as a Shortcut.

@Paul Black
I don't get it on one line either, Command Prompt doesn't seem to have the same WordWrap as Notepad does.

Had you had the opportunity to test the command to see whether it displays results for CSM?
UEFI native (without CSM)
UEFI hybrid (with CSM)

PowerShell.exe -executionpolicy bypass -Command "Write-Host 'The Motherboards Firmware is:'$env:firmware_type

I took out the double quotes and that worked, thanks.

The following is the simplest way to get it: BcdEdit|Find "EFI">Nul&&Echo UEFI is used||Echo Legacy is used

The above code works in elevated Command Prompt.

Thanks Matthew.

The output on yours IS on one line though. What I meant was that the output either looked like one of the following . . .

Code:

The Motherboards Firmware is:
Legacy

Code:

The Motherboards Firmware is:
UEFI

I always tend to over complicate these sort of things when they have a far simpler answer. Anyway, I went with the code that Matthew posted.
Thanks everyone.

@Paul Black, the following is an alternative that works in a batch file without administrative privileges:

For /f "Delims=" %%# in ('PowerShell $env:firmware_type') Do Echo Firmware is: %%#

Thanks.
