Want to install Windows 11 on an unsupported PC with no TPM 2.0 or old CPU? 🖥️ No worries! You can bypass Microsoft’s requirements with safe tweaks. Here’s the full step-by-step guide. ⚙️
📋 Step 1: Check Why Your PC Is Unsupported
Common reasons your PC may be unsupported:
- No TPM 2.0 or Secure Boot
- Old CPU not in Microsoft’s list
- Low RAM or disk space
Don’t worry—you can still install Windows 11 with minor registry tweaks.
💿 Step 2: Download the Windows 11 ISO
- Visit the official page: Microsoft ISO download
- Select “Download Windows 11 Disk Image (ISO)”
- Save the file to your PC
You can also use Rufus to create a bootable USB with TPM check disabled (more below).
🛠 Step 3: Bypass TPM and CPU Checks
Option 1: Registry Bypass (manual)
- Open Registry Editor (
regedit) - Go to:
HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup - Create a new DWORD (32-bit) value named:
AllowUpgradesWithUnsupportedTPMOrCPU - Set its value to 1
This lets you install via the setup.exe file inside the ISO.
🧰 Step 4: Use Rufus (Recommended Method)
- Download Rufus
- Insert a USB drive and select the Windows 11 ISO
- In Rufus, choose the option to disable TPM, Secure Boot, and RAM requirements
- Create the bootable USB and install as usual
This method is fast, automatic, and beginner-friendly.
🔁 Step 5: Boot and Install Windows 11
- Plug in your bootable USB
- Restart your PC and enter BIOS (usually F2, F12, Del)
- Select USB as first boot device
- Follow the on-screen installer to finish
You’ll now have Windows 11 running on your unsupported device!
⚠️ Note: Potential Risks
- No official updates in future (Microsoft may block)
- May miss security patches or compatibility features
- Backup your data before continuing!
Installing Windows 11 on unsupported hardware is 100% possible with safe tweaks like registry edits or tools like Rufus. Just proceed with care and enjoy the new OS experience! 💻🚀
