How to Install Windows 11 on Any Unsupported PC (Bypass TPM 2.0 & Secure Boot in 2026)

Can You Run Windows 11 on Unsupported Hardware?

Yes. Although Microsoft officially requires TPM 2.0, Secure Boot, and an 8th-Gen Intel or Ryzen 2000 processor, millions of computers with older hardware run Windows 11 smoothly without performance degradation.


Method 1: Create a Bypass USB with Rufus (Recommended)

  1. Download the official Windows 11 ISO from Microsoft's website.
  2. Download the free, open-source tool Rufus (version 4.0 or higher).
  3. Insert a USB flash drive (8GB or larger) and open Rufus.
  4. Select your Windows 11 ISO file.
  5. When you click START, Rufus displays a customization modal. Check the box:
    ☑️ Remove requirement for 4GB+ RAM, Secure Boot and TPM 2.0
  6. Boot your PC from the USB and install Windows 11 normally. The setup wizard will skip hardware verification.

Method 2: In-Place Upgrade Registry Bypass

If you want to upgrade an existing Windows 10 installation without formatting:

  1. Press Win + R, type regedit, and hit Enter.
  2. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
  3. Right-click > New > DWORD (32-bit) Value.
  4. Name it: AllowUpgradesWithUnsupportedTPMOrCPU and set its value to 1.
  5. Run setup.exe from your mounted Windows 11 ISO.

Activating Windows 11 on Older PCs

Once installed, enter your Windows 11 Pro Retail Key in Settings > Activation to unlock personalizations, updates, and lifetime security patches.

If your hardware struggles with background services on Windows 11, consider deploying Windows 11 Enterprise LTSC 2024 — Microsoft's official stripped-down channel without bloatware, telemetry overhead, or forced feature updates — or fallback to a rock-solid Windows 10 Pro Retail License.
