Get Windows 10 Pro, it's better. As for online security, be sure that if you go to a site that sells stuff, if it doesn't start with "https://", run! it doesn't matter if it changes to https:// when you click on the button to check out. it's too late by that point. Hackers could be monitoring the traffic and see everything you type. It's called a man-in-the-middle attack. A site has to be in secure mode from the moment you get the first page, otherwise it may not be secure at all. I've been saying this for years, and my site has been secure from the first page hit for several years. It's only in the past two or three years that I've seen business sites, including 3D sites, but even much bitter sites, to start doing this. And some big sites still don't get it. Staples only recently wised up. I just noticed. Last time I checked, only a few months ago, they still were unsecure on the store page until you clicked on the cart to checkout. My card was hacked twice at their site over the years. After the second time, I stopped ordering ink online. I'd go to their store and order it there.
