Rufus 4.12 Beta is out with better Dev Drive detection and ISO fixes

Rufus is a great utility for creating bootable drivers, which, among Windows users, is primarily known for its ability to bypass plenty of Microsoft's annoyances, such as forced BitLocker encryption, forced hardware requirements, forced Microsoft Account and online initial setup, and a lot more. Its latest update, version 4.12 (currently in beta), brings several improvements over the previous release, which was released in October last year.

Rufus 4.12 Beta does not contain any new features, but there are several Windows-related and general enhancements. For example, the app is now better at detecting Dev Drives and understanding their layouts. It has also received improved ISO extraction error and conflicting process reporting, a fix for a security vulnerability in Fido script execution, fixes for errors when saving images to paths with spaces, and more.

Here is the full changelog:

• Filter out the new Bitdefender VHDs
• Filter disallowed characters in local account names
• Improve Microsoft Dev Drive detection (#2873, courtesy of @MartinKuschnik)
• Improve the pre-formatting partition cleanup code
• Improve error reporting on ISO extraction issues
• Improve detection of drives with long hardware IDs (typically SSDs) (#2894)
• Improve conflicting process reporting
• Improve support for Nutanix (#2884) and umbrelOS ISOs
• Fix a TOCTOU vulnerability in Fido script execution (CVE-2026-2398, reported by @independent-arg)
• Fix replacement vulnerabilities for diskcopy.dll and oscdimg.exe
• Fix FFU image creation being erroneously invocated, when trying to save an ISO image (#2889)
• Fix saving of ISO images to paths that contain spaces (#2829)
• Update UEFI:NTFS and UEFI DBXs to latest
