Why You See “This PC Can’t Run Windows 11”

Microsoft introduced strict hardware requirements for Windows 11. If your PC doesn’t meet them, the installer blocks the upgrade.

Common causes include:

• TPM 2.0 disabled
• Secure Boot turned off
• Unsupported processor
• Legacy BIOS mode enabled
• Insufficient RAM or storage

1. Check Windows 11 Compatibility

Before changing settings, confirm your PC meets the minimum requirements.

• 4GB RAM minimum
• 64GB storage
• TPM 2.0 support
• UEFI + Secure Boot
• 64-bit compatible processor

You can use Microsoft’s PC Health Check tool to scan your computer automatically.

Tip: Many computers already support TPM and Secure Boot, but they’re disabled in BIOS settings.

2. Enable TPM 2.0 in BIOS

TPM (Trusted Platform Module) is one of the biggest reasons users see this error.

To enable TPM:

1. Restart your PC
2. Open BIOS (usually F2, DEL, or F12)
3. Go to Security settings
4. Find TPM, PTT, or fTPM
5. Enable it and save changes

After restarting, try running the Windows 11 installer again.

3. Turn On Secure Boot

Secure Boot helps Windows verify trusted startup files during boot.

To enable Secure Boot:

1. Open BIOS settings
2. Go to Boot options
3. Find Secure Boot
4. Enable it
5. Save and restart your PC

Important: Secure Boot works only in UEFI mode. Legacy BIOS mode must be disabled.

4. Convert Legacy BIOS to UEFI

If your system uses Legacy BIOS mode, Windows 11 may refuse installation.

You can safely convert using:

mbr2gpt /convert /allowfullOS

Then:

• Switch BIOS mode to UEFI
• Enable Secure Boot
• Restart the installer

5. Install Windows 11 on Unsupported PCs

If your hardware still isn’t officially supported, you can bypass restrictions using modified installation media.

Warning: Unsupported installations may not receive all future Windows updates.

Many users use Rufus to create a bypass-enabled Windows 11 USB installer.

By enabling:

most users can install Windows 11 successfully without replacing their computer.
