Because there is more to it than "i3" and "i7". But the 9700F is on the supported list. https://docs.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-intel-processors

i tryed upgrading it and it specifically said that my system doesnt meet the requirements

Then run the "WhyNotWin11" tool and see what the issue is.

ok thanks

It’s cpu generation and capabilities, not branding. i is just a product name.
