How to Use Rufus to Bypass Windows 11 System Requirements (Safely, and with Sources)
Microsoft set strict hardware bars for Windows 11—TPM 2.0, Secure Boot, supported CPUs, etc. If you’ve got a perfectly good PC that misses one or two checks, Rufus can create a Windows 11 USB installer that relaxes those checks so you can install anyway. This guide shows how to do it, plus the risks and official caveats.
⚠️ Important: Installing Windows 11 on unsupported hardware is not supported by Microsoft. You may encounter compatibility issues and may not be entitled to updates or support. Proceed only if you understand and accept those risks.
What is Rufus (and why use it)?
Rufus is a small, trusted Windows utility for making bootable USB drives. It includes options to create a Windows 11 installer that bypasses TPM 2.0, Secure Boot, CPU, and RAM checks—no manual registry edits required. Download it only from the official site or the Microsoft Store listing.
What you’ll need
- A USB flash drive (8 GB or larger).
- A Windows 11 ISO (download from Microsoft).
- Rufus (latest version).
You can confirm Microsoft’s official Windows 11 requirements here if you’d like to see exactly what your device is failing.
Step-by-step: Create a “requirements-bypassing” Windows 11 USB
- Download Rufus
Get it from the official site (portable version is fine) or its Microsoft Store page. - Download the Windows 11 ISO
Use Microsoft’s media download page (or the Media Creation Tool) to obtain a clean ISO. (Any up-to-date Windows 11 ISO works with Rufus’s bypass options.) For background on requirements, see Microsoft’s official docs. - Run Rufus and select your USB
Launch Rufus, choose your USB drive, and click Select to point Rufus at your Windows 11 ISO. - Enable the extended/bypass options
When Rufus detects a Windows 11 ISO, it will offer Extended Windows 11 Installation options. Check the boxes to remove requirements (TPM 2.0, Secure Boot, 8 GB RAM, and/or CPU family). This UI is explicitly documented in independent how-tos (with screenshots). - Click Start
Rufus will write the installer to your USB. Boot from it and install Windows 11 as usual. (If you’re upgrading in place, Rufus can also craft media that relaxes the checks during setup.)
What about doing it “the Microsoft-approved” way?
Microsoft publishes a narrowly scoped registry setting that allows upgrades on PCs with TPM 1.2 but an unsupported CPU (AllowUpgradesWithUnsupportedTPMOrCPU). Rufus is simpler and covers more checks, but if you prefer staying close to Microsoft’s guidance, consult the official note and use the registry method.
Known risks and trade-offs (read this!)
- Support & updates: Microsoft warns that installing on unsupported hardware is “not recommended,” may result in issues, and may not be entitled to receive updates. Many users do receive updates, but it’s not guaranteed.
- Future changes: Each Windows release can tweak checks. Re-creating media with the latest Rufus generally restores the bypass if Microsoft changes setup logic. (Rufus development notes and issues indicate ongoing support for these options.)
- Get Rufus from trusted sources only: Fake download sites exist; stick to rufus.ie or the Microsoft Store listing.
Extra tips
- If you still want to verify eligibility, run Microsoft’s PC Health Check app. It will tell you exactly which requirement you’re failing.
- If you’re staying on Windows 10 for now, be aware of the end of free security updates and the ESU program timeline, which may affect your upgrade urgency.

Bottom line
Rufus gives you a practical path to install Windows 11 on capable older machines by bypassing setup checks. Just weigh the convenience against the lack of official support, ensure you keep good backups, and always download Rufus from its official channels.
