I have an old computer at home. The CPU and motherboard do not support the installation of Windows 11. Win10 is installed without any problems. The hardware configuration is sufficient. Why can't I install Windows 11? Windows 11 has strict requirements for computers. One is TPM 2.0, and the other is whether the CPU supports it. But it doesn't matter. Even if the installation requirements are not met, you can force the installation of Windows 11. However, Microsoft has warned that if Windows 11 is forced to be installed, it will cause irreversible damage to the computer and Microsoft will not be responsible.
