Same! I installed W10 in 2016 too, when I built a new Intel 6th Gen system. Just kept on working until earlier this year when the motherboard died. Got a new 12th Gen chip and motherboard from a different vendor, stuck my seven year old boot drive in, entered the bitlocker key, and... it just worked. New drivers installed once I was back online and I just carried on as before. It genuinely surprised me how robust 10 is.

Eventually I ruined things this summer by accepting the 11 upgrade. I was tempted by windows subsystem for android.
11 worked ok and I found the UI changes tolerable, but after a month I started getting bluescreens I couldn't fix, so this week I finally gave in and wiped my antique install from the boot drive and installed a fresh copy.
It bluescreened pretty quickly, I figured the issue was almost certainly due to a particular piece of software I used. Removed that and it's been stable since. I could probably just restore my last backup, remove the problem program and continue. But I guess I was due a clean install, and while it wasn't laggy or slow before, it does feel a little snappier.
