All well and good. You are computer equipped, not stripped.
Then why are you using Windows 7 to get on the internet? You say Windows 7 might be the source of your problems w email programs.
I am typing right now on a 2017 i5-8400 desktop. I knew that it would be Windows 11 upgradeable.
My Win 7 was also upgradeable. I received many emails from MS to upgrade to Win 10 for free. I refused, because I’d heard horror stories of people upgrading, after which their computers didn’t work. I figured, I’ll stick with what works.
