Windows 11 requires TPM 2.0 to be installed on a PC, but many older machines lack this or have it disabled in the BIOS. Fortunately, there are solutions that allow you to install Windows 11 anyway. Here we explain what TPM is, why the requirement exists and how to install Windows 11 without TPM 2.0.
What is TPM 2.0?
TPM (Trusted Platform Module) is a security chip used for:
- BitLocker drive encryption
- Windows Hello
- Secure boot
- Protection against rootkits and firmware attacks
Windows 11 uses TPM to provide better built-in security.
Check if you already have TPM
- Press Win + R
- Type tpm.msc
- Press Enter
If TPM is disabled, you can enable it in the BIOS. It is often called:
- Intel PTT
- AMD fTPM
Method 1: Install via modified USB
The easiest method is to create an installation USB that removes the hardware requirement.
- Download Windows 11 ISO
- Use a tool that creates a USB without TPM requirements
- Boot the PC from the USB
- Install Windows as usual
Method 2: Registry solution during installation
- When you get the error message, press Shift + F10
- Type regedit
- Go to:
HKEY_LOCAL_MACHINE → SYSTEM → Setup - Create key: LabConfig
- Create DWORD values:
- BypassTPMCheck = 1
- BypassSecureBootCheck = 1
- BypassRAMCheck = 1
Close and continue the installation.
Important to know
- The PC is considered unsupported by Microsoft
- Some future updates may be blocked
- The security level will be lower
When does this make sense?
- Older gaming PC that is still powerful
- Test machines
- PCs without sensitive data
After installation, Windows must be activated
Conclusion
TPM 2.0 is a security requirement in Windows 11, but it is still possible to install the system on older hardware. With the right method, you can give new life to a powerful PC and run Windows 11 without problems.
