Installing Windows 11 on unsupported hardware, including CPUs that do not meet the minimum requirements, can be done through various methods, such as using the DISM tool as you described. However, Microsoft has set these minimum requirements for a reason, primarily to ensure the security and stability of the operating system. By bypassing these requirements, users may miss out on important security updates and features that are designed to work with supported hardware.
While this approach may reduce e-waste by allowing older hardware to run Windows 11, it does come with risks, including potential vulnerabilities and lack of support from Microsoft. The decision to allow such installations is not explicitly endorsed by Microsoft, and users should be aware of the implications of running an unsupported version of the OS.
Ultimately, while there may be ways to install Windows 11 on unsupported CPUs, it is important to consider the trade-offs involved in doing so, especially regarding security and system performance.
