Just heard about this the other day: "0patch".
If you want an extra layer of security for your Windows machine, and you're using an unsupported OS like Windows 10 will soon be, or if you're still a fellow 7 Omega Chad, the guys that run this service are a team that provide private patches to keep your computer secure. They seem to go after all sorts of problems that Microsoft also labels "won't fix" or are dragging their feet in releasing fixes for.
It's not just the OS, too, but tons of exploits in common programs that don't get regular support anymore. You have to pay a subscription for anything more than just the basic Windows zero-day patches, but the price is not too shabby for just an individual machine. https://0patch.com/
