Compatibility with Windows XP and Vista

FlashBoot is fully functional under Windows XP and Windows Vista. FlashBoot does not mount registry hives, FAT filesystems, WIM and VHD images via Windows kernel. These features are implemented inside FlashBoot, without invocation of platform-specific tools.

If you run FlashBoot under Windows XP, formatting in UEFI mode will still work, but because resulting USB thumbdrive will have GPT layout (instead of usual MBR layout), you won't be able to view list of files on the resulting USB thumbdrive in Windows XP File Explorer. Under Windows Vista/7/8/8.1/10 resulting USB thumbdrive will be perfectly viewable. FlashBoot will still recognize USB thumbdrive with GPT layout even in Windows XP if you need to reformat it.
