How to install Windows 11 without TPM [Bypass CPU requirements]
Windows 11 is a 64-bit only OS. Like macOS, Microsoft too has moved to supporting only 64-bit systems with its newest operating system. In addition to the 64-bit requirement, Windows 11 also requires secure boot UEFI and TPM 2.0 on a system in order to run. For many users, the TPM chip version is what blocks them from upgrading to Windows 11.
Install Windows 11 without TPM
The TPM chip is a hardware component. If your system doesn’t have one, chances are you need to buy a new system. This chip isn’t exactly something you can upgrade like RAM. Your motherboard may not support a newer version of the chip. That said, you can bypass Windows 11’s requirement for the chip.
To do this, it is best to upgrade to Windows 11 from Windows 10. Before you upgrade, you must edit the registry and tell Windows 10 to bypass the TPM requirement.
This is generally safe to do but we strongly encourage you to backup important files on your system before you proceed. If you can, create a restore point. This will work for systems with both supported and unsupported gaming CPUs.

Conclusion
Microsoft generally doesn’t create software that forces users to buy new hardware. If you have a system that is too old to have a TPM 2.0 chip, you should consider buying a new system. The TPM chip adds improved security to your system and going forward, you will need it. It’s also possible that Microsoft will patch this work around leaving you in a bind.
