Yes:

Code:

M:\wim-mount\Windows\System32\Boot>dir

Directory of M:\wim-mount\Windows\System32\Boot

10.07.2015  14:04    <DIR>          .
10.07.2015  14:04    <DIR>          ..

10.07.2015  13:30         1 019 592 winresume.efi

I have managed to create a UEFI bootable USB-stick from the ISO version of the same image.
