There is a service called 0patch that offers microcode patching for EoL windows versions, for about 30 bucks a year I’m still getting updates for my Win7 gaming rig. Never had an exploit or hijacking and I pirate quite a bit on that PC.

Plan on getting one for my Win10 daily driver next year.

And as for trust: Microsoft has awarded 0patch for several zero day exploits, and have used their patches in official releases before so not only are they trustworthy, they are literally faster at finding exploits than MS themselves.

Full disclosure: No relationship with the company other than as a happy paying customer.
