If the PC health check app or Windows 11 setup is showing you “This PC doesn’t meet Windows 11 system requirements” or “This PC can’t run Windows 11“. Then no worries, still you can install Windows 11 on an unsupported PC/Laptop.

But before start following this article to install Windows 11, first, check if TPM support is available on your PC/laptop or not. Because, if TPM is supported by your system, then by enabling it you can install Windows 11. Though, if your processor isn’t currently supported for Windows 11, then here’s how, you can install it. Alternatively, you can install rectify11 on an old laptop. It is a modified version of Windows 11, that works without TPM and Secure Boot.
