Just the exe: no installation and no other files needed. Requires Windows 8 or later and administrator rights.

These builds are not code signed, so Windows SmartScreen may warn you the first time you run Mufus: click More info, then Run anyway.

What's new compared to Rufus 4.15

• Multi-drive mode: click the stacked drives button at the end of the Device row, tick up to 10 drives and press START. The drives are written at the same time, with a per-drive progress window and per-drive results.
• All the Rufus questions and options are asked once and apply to every drive. Drive specific defaults (cluster size, volume label) are worked out for each drive, and every drive is checked before anything is written.
• Single drive mode is unchanged from Rufus.
• Mufus and Rufus can't run at the same time.

See the README for the details.

Tested

Written to 3 drives at once (virtual disks): non bootable FAT32, FreeDOS, DD image, UEFI ISO (GPT and MBR), and an official Windows 11 26H2 ISO with the TPM/Secure Boot/RAM, online account, data collection and BitLocker customizations (every file verified against the ISO on every drive). Also tested: cancellation, single drive mode and blank drives. Physical USB drives have not been tested yet.
