Rufus 4 is the first update to drop Windows 7 (earlier Rufus 3.22 dropped ISO downloads on Windows 7). From now on, creating bootable USB drives with Rufus requires Windows 8, 8.1, 10, or 11. Also, the app now defaults to a 64-bit executable, but x86 and ARM versions are still available for download. Finally, the developer says old Rufus versions may be unable to update correctly, hence the jump from version 3 to 4.
