2 things
i will not upgrade
when the date comes what should i expect with my pc? will it act the same as it would?
Lack of security updates would make your pc very susceptible to malware, but iirc there's regular fanmade updates or something for windows 7 that will probably also be a thing for 10 soon
Still, dualboot Linux in the meantime and see how you like it. I switched back when they released windows 11 and I figured they'd keep trying to force me to "upgrade"
