I don't see how you can say that, unless you've not actually used Windows ME and/or 10 for any significant period of time.
Windows 10 is very well polished. It's also the first windows where most of the user's gripes are stuff added on top of it (telemetry, simplified/restricted update system, ...).
Windows ME, by comparison, was so bad that merely leaving it running would end up causing PC Health crashes.
Well, aside from Windows Defender steadfastly turning itself off because it thinks I have a different AV package installed (I don't) and "helpfully" redirecting me to uninstall the offending software first. Only there is no other AV package to uninstall.
I have so far been absolutely unable to find any sort of resolution to this issue, short of a full reinstall.
But the kernel and system side are miles above ME. We're talking about a time when you could turn a system on, sit there and watch it for a couple hours without touching anything, and it would crash itself.
