You would be better off to “downgrade” to win 7. I have had that on my laptop for ages (although XP was their best OS)). FWIW, I never allow my computer to update, and took the anti virus off it years ago on the advice of my son in law, who runs the IT dept in a Hawaii school. I go to some very sketchy websites (XXX stuff really), haven’t had a problem at all.
So I have no idea what all the noise is about security patches and being at risk, and for years and years a lot of people say that its an issue. Not w/ me, works fine all the time. I had 8 on a laptop and took it back, not a good OS. 7 will let you set things up the way YOU want them, not how Microsoft wants it. I also got rid of Chrome (slow and bloated) and went to Brave a long time ago. It stops trackers, has shields, and is setup virtually identical to Chrome but works much faster. Combined that w/ proton email that is double encrypted and their VPN (all free), it’s a sweet, secure machine.
