Rufus 4.15

About Rufus

If you're looking for a reliable, free tool to create bootable USB drives on Windows, Rufus is probably already on your radar. It's a lightweight, no-fuss utility that turns any USB stick into installation media for operating systems like Windows, Linux, or even macOS. Developed by Pete Batard, Rufus emerged as DVDs faded from popularity and USB drives became the standard for system installs and repairs. And in 2026, it's still the tool most people reach for first.

Why Rufus Still Wins

One of the best things about Rufus is its simplicity. You don't need to be tech-savvy to use it, just plug in your USB, select your ISO file, and let the tool do the rest. It supports a wide range of file systems and partition schemes, including MBR, GPT, UEFI, and BIOS, making it compatible with almost any computer setup. Be aware, though: the process will wipe your USB drive, so always back up your data first.

Despite being Windows-only, Rufus can create bootable drives for other platforms. It's also portable, meaning you can run it directly without installation, which is super handy for troubleshooting on the go. The developer maintains regular updates and is responsive to user feedback, and since it's open-source, the community can contribute improvements too. Rufus is still the fastest, most reliable way to write an ISO from a Windows machine, especially for Windows media creation.

What's New in Rufus 4.15 (And Why It Matters)

The latest version, Rufus 4.15, was released on June 30, 2026. It's still tiny, about 1.9 MB, and packed with useful improvements. The headline feature is RISC-V 64 support for UEFI:NTFS, which means Rufus can now create bootable drives for RISC-V-based systems. That's a forward-looking addition for anyone experimenting with alternative architectures.

More importantly for most users, Rufus 4.15 fixed several bugs related to the Windows 11 installation bypass feature. If you've been using Rufus to install Windows 11 on unsupported hardware (no TPM 2.0, no Secure Boot, older CPU), version 4.15 improves the guards for the silent installation option and fixes issues that could cause the bypass to fail. The update also improves cancel responsiveness during write retries and adds better progress reporting for compressed image extraction.

On the security side, 4.15 patches an integer overflow and an unrestricted XML entity expansion vulnerability in the ezxml parser. These are the kinds of bugs that could theoretically be exploited through malicious ISO files, so updating is genuinely important. And if you're still on Rufus 4.11 or below, you need to update immediately, there's a known local privilege escalation vulnerability (CVE-2026-23988) that allows an attacker to replace the Fido PowerShell script with a malicious one because Rufus writes it to the %TEMP% directory without locking it.

The Windows 11 Bypass: Still the Killer Feature

Let's be honest, one of the main reasons people use Rufus is to install Windows 11 on hardware that Microsoft says isn't supported. Rufus has built-in options that let Windows 11 ignore the hardware requirements, meaning you can upgrade your computer anyway. When you create a Windows 11 USB installer with Rufus, you can remove TPM 2.0, Secure Boot, RAM, and CPU checks with a single checkbox. Version 4.14 added a "Quality of Life" option that disables Teams, Outlook, Copilot, and other Microsoft forced nuisances during installation, plus a Silent installation mode that automatically installs Windows on the first detected disk without any prompts. If you're deploying Windows 11 on multiple machines, that's a massive time-saver.

Rufus vs. Ventoy: The Honest Comparison

Here's where things get interesting. Rufus is still the fastest single-image writer for Windows. It's simple, it's reliable, and for creating a one-off Windows installer, it's hard to beat. But there's one limitation that's become more annoying over the years: you can only store one bootable ISO per USB drive. If you want to switch from a Windows 11 installer to a Linux Mint rescue drive, you have to reformat the whole thing and start over.

Ventoy solves that problem. It's a free, open-source tool that lets you drop as many ISO files as your USB drive can hold onto a single partition, and you choose which one to boot from a menu at startup. No reformatting, no rewriting, just drag and drop. For anyone who regularly works with multiple operating systems or keeps a diagnostic toolkit on a USB, Ventoy is a game-changer. The trade-off? Ventoy requires an initial setup that erases the drive, and it adds a couple of extra boot screens that some users find annoying. It's also slightly slower for single-image writes compared to Rufus.

BalenaEtcher is the third option in this space. It's cross-platform (Windows, Mac, Linux), has a clean, modern interface, and validates writes after completion. But it's slower than Rufus and lacks the advanced Windows 11 bypass features. It's great for beginners who just want to flash an ISO and don't need any extras.

So which should you use? If you're creating a dedicated Windows 11 installer with bypass options, Rufus wins. If you want a multi-boot USB that holds every OS you need, Ventoy is the better choice. If you want a simple, cross-platform flasher that just works, Etcher has you covered. They're not really competitors, they're different tools for different jobs.

Rufus is still the gold standard for creating bootable USB drives on Windows. It's tiny, fast, portable, and free. The Windows 11 bypass features are genuinely useful, the 4.15 update fixed important bugs, and the RISC-V support shows the developer is still actively pushing the tool forward. Is it perfect? No. The single-ISO limitation is real, and if you're juggling multiple operating systems, Ventoy is the smarter workflow. But for most people, most of the time, Rufus is exactly what you need. Just keep it updated, especially if you're still on an older version with that privilege escalation vulnerability.
