No CPU that system will take, is supported by Windows 11. You will need to install Windows 11 without a supported CPU and TPM: [URL] The one caveat:  Microsoft's public statement that Windows 11 is likely to be updated at some point, such that unsupported platforms are cut off from future updates.  
Hi guys   I want to know if any of you have an idea for to solve the problems related to the installation of Windows 11 on the Latitude E6430 (laptop that it's still fine at the moment!), with reference to the upgrade the TPM (2.0) and processor (Intel i5 - 3340M - 2.4Ghz).  Thanks, Max
