UEFI is more and more common on new computers.
It was time for an update within QuickPE to support UEFI.
Once you have generated your Windows X64 UEFI compliant iso, I suggest using Rufus to burn it to a USB key.
Make sure to select GPT for UEFI as partition type and FAT32 as filesystem or else you’ll be booting in BIOS mode.
