Take the free download from microsoft, you might have to turn off a couple of things if you have a 2/3 year old computer.
As mentioned,there are good presentations on the web going into detail on what needs done.
In my situation I have a few laptops and desktop that came with windows 98 that I upgraded to XP, then Win 7 then to win 10, by pirating vista drivers, they said I couldn't do that but they work fine for what I want to do with them, (no gaming/videos)
The solid state inexpensive
hard drives now available are a good improvement.
All that said, I have a new dell laptop purchased in January with win 11 installed.
Not a lot of changes in 11, compared to win 10.
My old dinosaurs will just go offline come next year but I will continue to use then for the few programs installed on them.
Microsoft does have an extended support subscription for 1 year for Win 10
home users, cost $30 for critical security updates , no bug fixes or tech support.
My computer knowledge is but a grain of sand on the earth's surface.
