If your PC is indicated as not compatible with WIndows, it may be possible to upgrade your hardware to make it compatible, if not, you can sign up for the free ESU (Extended Security Updates) so Windows 10 would continue to receive security updates up to October 2026.
I will check if your hardware can be upgraded for Windows 11, click your Start Button, then just type msinfo and press Enter, please provide a screenshot of the resulting System Information window.
